Unit 23 · Advanced Grammar and Usage

Read this: "The train was late; nobody on the platform looked surprised." A period would be correct there. So would the word "and." The writer chose a semicolon because the two halves are really one thought: the lateness and the lack of surprise explain each other. Each half is an independent clause, a group of words with a subject and a verb that could stand alone as a sentence. That is the semicolon’s first and most important rule. Whatever sits on either side of it must be able to stand by itself.

The rule fails in a sentence like "The train was late; which surprised no one." The second half cannot stand alone, so it needs a comma, not a semicolon. The rule also matters with words like however, therefore, meanwhile and for example. These are conjunctive adverbs, and they do not have the joining power of and or but. "The train was late, however, nobody looked surprised" is a comma splice, two sentences stuck together with only a comma. Fix it with a semicolon before however and a comma after it: "The train was late; however, nobody looked surprised."

The semicolon has a second job that has nothing to do with joining sentences. When items in a list already contain commas, a reader cannot tell where one item ends and the next begins. Semicolons become the stronger divider: "The tour stops in Springfield, Illinois; Madison, Wisconsin; and Des Moines, Iowa." Without those semicolons, the sentence looks like a list of six places instead of three.

Some writers avoid the semicolon and get along fine with periods. Others use it in every paragraph. The mark is worth keeping for the moment when a period would break a connection you want the reader to feel. Overuse makes writing feel stiff; a single well-placed semicolon can make two sentences click together like a latch.

Here is a colon doing its job: "She packed three things: a map, a flashlight and her grandfather’s compass." Everything before the colon is a complete sentence. Everything after it delivers what that sentence promised. That is the shape of nearly every correct colon. The mark points forward, like an arrow, and says: here it comes. The most common colon error is putting one after words that cannot stand alone, as in "She packed: a map, a flashlight and a compass." Since "She packed" is not a complete thought about three things, no colon belongs there.

A colon can introduce a single word or a whole explanation, not just a list. "There was one problem: the bridge was gone." The colon makes the reader wait a half second and then lands the answer. Compare it with the semicolon. "The bridge was gone; we turned back" balances two ideas of equal weight. "There was one problem: the bridge was gone" sets up and then delivers. The semicolon is a hinge. The colon is a drumroll.

Colons also have fixed jobs. They follow the greeting in a formal letter: "Dear Dr. Ruiz:" (a comma is for personal letters). They separate hours and minutes, as in 7:45, and the parts of a ratio, as in 3:1. In a research paper, a colon usually introduces a block quotation, a long quotation set off from the paragraph. Should the first word after a colon be capitalized? Style guides disagree. Some capitalize when a full sentence follows; others do not. Pick one rule and hold to it through the whole paper.

A quick test before you type a colon: cover everything after it and read what is left. If those words make a sentence on their own, the colon is legal. If they trail off, delete the colon or rewrite. "The reasons are: cost and time" fails the test. "There are two reasons: cost and time" passes it.

"The bus—the one I had waited forty minutes for—drove past without slowing." The pair of long dashes cuts into the sentence, drops in a bitter detail, and lets the sentence continue. That mark is the em dash, named because it is about as wide as a capital M. Used in a pair, em dashes set off an interruption. Used alone near the end of a sentence, one em dash throws all the weight onto whatever comes after it: "He had one rule—never be late."

Three marks on the keyboard look alike, and editors care about the difference. The hyphen (-) is the shortest and joins words: well-known, twenty-one. The en dash (–), about as wide as a letter N, joins ranges and pairs: pages 12–18, the years 1871–1893, the Chicago–Detroit train. The em dash (—) is the longest and interrupts. In most word processors, typing two hyphens between words turns into an em dash. Book publishers usually close the em dash up tight with no spaces; newspapers usually put a space on each side. Either is acceptable if you do it the same way every time.

Dashes are loud. A comma pair around an interruption is quiet; a pair of parentheses whispers; a pair of dashes raises its voice. That makes the dash powerful and dangerous. A paragraph with a dash in every sentence sounds breathless, as if the writer cannot finish a thought. Save the dash for the interruption that matters or the ending that deserves a spotlight. Emily Dickinson built poems out of dashes, and her lines feel like someone catching her breath; in an essay, that effect wears out fast.

"The cafeteria (which had been closed since March) reopened on Monday." Take out the parentheses and everything inside them, and the sentence still stands: "The cafeteria reopened on Monday." That is the test. Whatever you put inside parentheses is an aside, a remark the reader could skip. If removing it breaks the sentence, the words were not an aside and do not belong in parentheses.

The end punctuation follows one rule. If the whole sentence is inside the parentheses, the period goes inside too: "We finished early. (No one complained.)" If the parenthetical sits inside a larger sentence, the period goes outside: "We finished early (no one complained)." Never put a comma before an opening parenthesis. If the sentence needs a comma at that point, it goes after the closing one: "After the vote (which took an hour), the meeting ended."

Academic writing uses parentheses for jobs that are not really asides: a page citation (Smith 42), a date, or the short form of a long name the first time it appears, as in "the Chicago Transit Authority (CTA)." After that first time, CTA alone is enough. These parenthetical uses are fixed by the style guide, not chosen for tone.

Now compare the three ways to interrupt a sentence. "The cafeteria, which had been closed since March, reopened on Monday" is neutral; the commas treat the fact as ordinary. "The cafeteria—which had been closed since March—reopened on Monday" is emphatic; the dashes make the closure a big deal. "The cafeteria (which had been closed since March) reopened on Monday" is quiet; the parentheses tell the reader this is background. Same words, three volumes.

Suppose a source says, "She refused the offer twice." You want to quote it, but your reader will not know who "she" is. You may not silently change the quotation to "Jane Addams refused the offer twice," because those are no longer the source’s exact words. Instead you write: "[Jane Addams] refused the offer twice." The square brackets are a promise. Everything inside them is yours; everything outside them is the source’s. A quotation is a kind of testimony, and brackets keep the testimony honest.

Brackets have several standard uses. They hold a word that clarifies: "The council voted against it [the stadium plan]." They hold sic, a Latin word meaning "thus," placed after an error in the original to show that the mistake is the source’s, not yours: "the state capitol in Springfeild [sic]." They hold a note that you changed the look of the words: "[emphasis added]" after a word you italicized. And when one parenthesis must go inside another, most style guides switch the inner pair to brackets.

One small case divides the guides. If a quotation begins mid-sentence and you need a capital letter, some styles write "[T]he" to show the change, while others let you change the first letter without comment. Legal writing uses the brackets; most book and magazine editing does not. Your instructor’s guide decides. What no guide permits is using brackets to make a source say something it did not say. "The plan is [not] affordable" would be a lie in brackets.

A good habit: after you bracket, read the sentence as your reader will, and then read the original again. The bracketed version should change nothing except clarity. If the source’s meaning has shifted even slightly, drop the brackets and paraphrase in your own sentence with a citation instead.

Try reading this in one breath: "When the ice on the lake finally broke the ferry ran again and the island’s eleven families came ashore for the first time since January." Somewhere around "broke the ferry" a reader stumbles, because for a moment the ice seems to be breaking the ferry. Commas exist to prevent that stumble. The old advice to "put a comma where you breathe" is unreliable; readers breathe in different places. Commas follow the structure of the sentence, and the structure can be learned.

First rule: a dependent clause that opens a sentence gets a comma after it. "When the ice finally broke, the ferry ran again." Reverse the order and the comma usually disappears: "The ferry ran again when the ice finally broke." Second rule: a nonrestrictive clause, one that adds information without narrowing the meaning, is set off by commas; a restrictive clause, which narrows the meaning, is not. "The students who finished early left" means only the early finishers left. "The students, who finished early, left" means all of them left, and by the way they were early. Many American editors reserve "that" for restrictive clauses and "which" for nonrestrictive ones, though careful writers have long used "which" both ways.

Third rule: when a coordinating conjunction (and, but, or, so, yet, for, nor) joins two independent clauses, put a comma before it: "The ferry ran again, and the families came ashore." When the conjunction joins only two verbs with one subject, leave the comma out: "She read the report and signed it." Two other commas cause trouble by showing up where nothing needs them. Never split a subject from its verb ("The ferry that runs in winter, is small" is wrong), and never put a comma right after a conjunction that opens a sentence.

Here is the same scene punctuated by structure. When the ice on the lake finally broke, the ferry ran again, and the island’s eleven families came ashore for the first time since January. The mail, which had piled up in a canvas sack at the post office, filled the back of the truck. Nobody complained about the wait. The ferry captain, a woman named Ruth who had run the route for thirty years, said that the ice had been thicker than any she remembered, and she had records to prove it. By noon the island was empty again.

"We invited the mayors, a poet and a juggler." How many groups is that? Three, probably. But the sentence can also mean two mayors who happen to be a poet and a juggler. The comma that would settle it, placed before the "and" in a list of three or more, is the serial comma, also called the Oxford comma. "We invited the mayors, a poet, and a juggler" can only mean three groups. Whether that comma is required is the most argued-about question in American punctuation.

The dispute is between style guides, the rulebooks that publishers adopt. The Chicago Manual of Style, used by most book publishers, requires the serial comma, and so do the MLA and APA guides that most schools follow. The Associated Press Stylebook, used by most newspapers, leaves it out, partly to save space, and tells editors to add it only when a list would otherwise confuse. Both camps claim clarity. The Declaration of Independence lists "Life, Liberty and the pursuit of Happiness" with no serial comma, and no one has ever misread it.

The stakes are not always small. In 2017 a federal appeals court decided a case brought by delivery drivers in Maine over overtime pay. The state law listed the kinds of work that did not earn overtime, ending with "packing for shipment or distribution." Without a comma before "or," the court found the phrase could mean one activity, packing, rather than two, and it ruled for the drivers. Reports at the time put the settlement at about five million dollars. One missing comma, read closely, cost a company a fortune.

So what should you do? Use whatever guide your teacher or employer names, and use it every time. Then read each list for ambiguity, the possibility of two meanings. If a list could be misread with or without the comma, punctuation alone will not save it. Rewrite: move the item that looks like an appositive, a renaming phrase, to the front or end of the list. "We invited a juggler, a poet and the mayors" is safe under either rule.

"A small business owner" could be a short person who owns a business. "A small-business owner" is someone who owns a small business. The hyphen turns "small business" into one unit that describes "owner." Two or more words working together as a single adjective before a noun form a compound modifier, and the hyphen is what tells the reader to read them together: a well-known author, a twelve-year-old cousin, a first-place finish, an out-of-state license.

Two limits keep the rule from spreading everywhere. When the same words come after the noun, they usually go back to being separate: "The author is well known." "My cousin is twelve years old." And when the first word is an adverb ending in -ly, no hyphen is needed, because the -ly already announces that the word modifies the next one: a highly paid consultant, a badly damaged roof. Numbers from twenty-one to ninety-nine are hyphenated when spelled out, and fractions used as adjectives usually are too: a two-thirds majority.

A prefix is a word part attached to the front of a word, and most prefixes attach with no hyphen at all: nonprofit, preheat, coworker, misread. The hyphen returns in three situations. Before a capital letter: pre-Columbian, un-American, mid-July. When the same word without the hyphen already means something else: re-sign a contract is not resign from a job, and re-cover a chair is not recover from an illness. And sometimes when two identical vowels collide, as in anti-inflammatory, though many guides now close up re-enter as reenter. Dictionaries change on these; "e-mail" became "email" in most guides within a decade.

One more tool: the suspended hyphen. When two compounds share a final word, write the word once and leave the hyphens hanging: "first- and second-year students," "pre- and post-test scores." It looks odd the first time and saves the reader a repeated word every time after.

American style has a fixed rule that surprises many students: periods and commas go inside the closing quotation mark, even when they were not part of the quotation. "The plan failed," she said. He called it "a disaster." Colons and semicolons go outside: He called it "a disaster"; nobody argued. Question marks and exclamation points go inside only if they belong to the quoted words. The one exception matters in research papers: when a parenthetical citation follows a quotation, the period moves to after the citation: He called it "a disaster" (Ortiz 42).

Sometimes a quotation is too long, and you want only part of it. An ellipsis, three spaced periods, marks the words you removed from the middle: "The committee . . . voted to close the branch library." If the cut comes at the end of a sentence, most guides add the sentence’s period first, making four dots. You usually do not need an ellipsis at the start of a quotation; the reader assumes the source said things before. What you may never do is cut words in a way that changes the meaning. Turning "the plan is anything but affordable" into "the plan is . . . affordable" is not editing. It is lying.

Length changes the format. A prose quotation that runs more than four typed lines in MLA style, or roughly a hundred words in Chicago style, becomes a block quotation: indented from the left margin, with no quotation marks around it, introduced by a sentence ending in a colon. Inside any quotation, a quotation of someone else’s words takes single quotation marks: "The witness said, ’I saw nothing,’ and sat down."

Every quotation needs a way in. A signal phrase names the source and leads the reader to the words: According to the report, "the bridge cannot bear the load." A comma follows a short signal phrase; a colon follows a complete sentence; and a quotation woven into your own grammar needs no punctuation at all: The engineers warned that the bridge "cannot bear the load." Here is a cut done fairly. Original: "The committee, after meeting for three hours on a Tuesday night in a room with no working heat, voted to close the branch library on Halsted Street." Quoted: "The committee . . . voted to close the branch library on Halsted Street."

Herman Melville wrote a book called Moby-Dick, and it would appear in your essay in italics. Edgar Allan Poe wrote a short story called "The Tell-Tale Heart," and it would appear in quotation marks. The logic is size and independence. A standalone work, something published on its own, takes italics: a book, a play, a film, a television series, an album, a newspaper, a magazine, a website, a long poem such as Whitman’s Leaves of Grass. A work that lives inside something larger takes quotation marks: a chapter, an article, an episode, a song, a short story, a short poem such as Dunbar’s "We Wear the Mask."

There are cases where italics are impossible or unwanted. In handwriting, underline instead; underlining is the old typewriter signal for italics. Newspapers following AP style do not use italics at all and put nearly every title in quotation marks. Sacred texts (the Bible, the Quran) and foundational documents (the Constitution) are written plain, with no italics or quotation marks. The title at the top of your own paper is plain too: no italics, no quotation marks, no underline. Only titles of other people’s works get marked.

Then there is capitalization. Most guides use title case for titles in the text: capitalize the first and last words and every major word, and lowercase short articles (a, the), coordinating conjunctions (and, but) and short prepositions (of, in, to) in the middle. So: The Adventures of Huckleberry Finn, "The Road Not Taken." APA style does something different in its reference list, capitalizing only the first word and proper nouns. Once again the answer to "which is right?" is "which guide is your reader expecting?"

A working checklist for your next paper: is it a whole thing or a part of a thing? Whole gets italics, part gets quotation marks. Is it your own title, a sacred text or a founding document? Plain. Are you writing for a newspaper? Quotation marks for everything. And capitalize by the guide, consistently, from the first page to the works cited.

A copy editor reads a manuscript sentence by sentence, fixing errors, marking inconsistencies and questioning anything a reader might misread. Every publisher gives its editors a house style: the guide the company follows plus its own exceptions. Book publishers mostly use the Chicago Manual of Style, first published in 1906. Newspapers use the Associated Press Stylebook. Papers in literature and languages follow the MLA Handbook; papers in psychology and the social sciences follow the APA manual. None of these is the one true grammar. Each is a set of decisions made so that a whole publication reads as if one careful person wrote it.

For each manuscript, the editor also builds a style sheet, a running list of decisions made for that book alone: serial comma yes; email closed, no hyphen; numbers under one hundred spelled out; the character’s name spelled Katherine, not Catherine. The sheet exists because consistency matters more than any single choice. A reader who sees "toward" on page 10 and "towards" on page 12 begins, without knowing why, to trust the book a little less.

When a question comes up, an experienced editor works down a short ladder. Does the sentence mean what the author intended, read cold? That comes first, before any rule. Next, what does the house guide say? Then the dictionary, usually Merriam-Webster for American publishers. Then the style sheet: what did we decide last time? And last, the author’s voice; an editor who flattens every dash and semicolon into a period has fixed nothing and taken something. When the answer is not clear, the editor does not guess. She writes a query, a question in the margin to the author, exactly as the university press editor did with Dana’s list.

You will edit your own writing for the rest of your life, and you can borrow the same tools. Choose the guide your reader expects. Keep a half-page style sheet for each long paper: the comma rule you are using, how you cite, which spellings you settled. Read the draft once for meaning, once for sources and once for nothing but punctuation. The marks in this chapter are not decorations; each one is a small instruction to the reader, and the editor’s whole job is to make sure every instruction is the right one.

Two people look at the sentence "Me and him went to the store." The first says, "That is wrong; it should be He and I went." The second says, "Millions of English speakers say it that way every day, so it is part of English." Both are right about something. The first is speaking prescriptively, stating a rule about what writers should do. The second is speaking descriptively, reporting what speakers actually do. Grammar books are mostly prescriptive. Linguists, the scientists who study language, are mostly descriptive. The two groups have argued for two hundred years, and the argument is worth understanding because you will live inside it.

The descriptive view rests on a fact: language changes, and no rulebook has ever stopped it. English once had the word thou, and every dictionary lost it. Rules that were once fiercely enforced, such as never using the word contact as a verb, are now forgotten. A descriptivist notices that "Me and him went" follows a perfectly regular pattern that many speakers share, and that calling it wrong is really calling it nonstandard, which means outside the variety of English that schools and employers expect. That variety, Standard English, is not more logical than the others. It is the one with power behind it.

The prescriptive view rests on a different fact: readers judge. Priya did not care whether you’re for your was a natural variation. She cared that the letter was for a job. When you write for school, for work, for a grant or for a court, your reader expects Standard English, and a rule that says "use it here" is not snobbery but advice about the room you are in. The best writers hold both views at once. They know the rules, they know which rules are really just habits, and they know that following the expected rules is a courtesy to the reader that costs the writer nothing.

A usage question, then, is rarely "is this correct?" It is "is this what this reader, in this setting, expects?" That reframing will get you through most of the disputes in this chapter. It also tells you what to do when a rule seems silly: follow it where a reader expects it, drop it where no one does, and be able to say why.

"She decided to quietly leave." For more than a century, teachers marked that sentence wrong because an adverb sits between to and leave, splitting the infinitive. The rule appeared in the 1800s, when some grammarians modeled English on Latin, where an infinitive is one word and cannot be split. English is not Latin. Writers had been splitting infinitives since the 1300s, and every major American style guide now says the split is fine when it reads more naturally. "She decided quietly to leave" is stiff and slightly unclear; the split version is better.

The ban on ending a sentence with a preposition has the same history and the same fate. "Where are you from?" is normal English; "From where are you?" is nobody’s speech. A related rule said never to begin a sentence with and or but. Good writers have always done it, and doing it is often the clearest way to mark a turn. None of these was ever a rule of English grammar. Each was a rule of taste that some people mistook for a law.

The newest change is singular they. English has no common pronoun for one person of unknown or unstated gender, and for centuries writers filled the gap with they: "Someone left their umbrella." Shakespeare did it, and so did Jane Austen. Grammarians of the 1800s pushed "he" as the generic pronoun, and schools taught it until the late twentieth century. The guides have since reversed. The Associated Press Stylebook permitted limited singular they in 2017, the Chicago Manual of Style’s seventeenth edition (2017) accepted it in speech and informal writing, and the APA manual’s seventh edition (2019) endorsed it in all writing. Merriam-Webster named "they" its Word of the Year for 2019. Singular they also serves people who use it as their personal pronoun, and using a person’s stated pronoun is now standard courtesy in most workplaces.

The lesson is not that rules do not matter. It is that a rule has a history, and knowing the history lets you follow it or set it aside on purpose. If you split an infinitive in a college paper, no careful reader will blink. If you write "Each student must bring their own laptop," the APA will nod. But an older reader, or a very formal setting, may still expect the old forms, and you can choose to give them what they expect. That choice, made knowingly, is what fluency looks like.

The grocery sign says "10 items or less." A certain kind of reader winces and wants "fewer," because the traditional rule says fewer for things you count (fewer coins) and less for things you measure (less money). Dictionaries note that less with countable nouns has been in use for a thousand years, and "10 items or less" bothers almost no shopper. Still, in a college paper or a job application, "fewer" is the safe choice, because the reader who winces might be the one grading. This is the pattern of a contested usage: both forms are common, one is safer with careful readers.

Who and whom follow the same pattern. Whom is the object form ("To whom did you speak?"), and it is fading from speech. Many editors now accept who in most positions except right after a preposition. Hopefully as a sentence adverb ("Hopefully, the bus is on time") was fought over for decades and is now accepted by nearly every guide. Data was once treated only as a plural ("the data are"), and many scientific journals still require it, while most general writing treats it as a mass noun ("the data is"). Literally has come to mean "figuratively" in casual speech ("I literally died"), and dictionaries record that sense, but in writing it still makes careful readers laugh at you, not with you.

Then there are the pairs that are not contested at all, only confused: affect (usually a verb) and effect (usually a noun); lie (to recline) and lay (to place); imply (the speaker hints) and infer (the listener concludes); irregardless, which dictionaries list as nonstandard and which no guide accepts in formal writing. These are not matters of taste. Getting them wrong in a letter is the kind of thing Priya notices.

For any usage you are unsure of, ask three questions. Is it contested, confused or simply a rule I never learned? Which way would the reader I am writing for lean? And can I sidestep it? "There are fewer errors" and "there are less errors" both vanish if you write "there are not as many errors." Sidestepping is not cheating. It is what professionals do when a fight is not worth having on the page.

Here is the same news three ways. To a friend: "got the job!!! start monday." To a teacher who wrote a recommendation: "I wanted to let you know I got the internship. Thank you for the letter; I start Monday." To the firm’s human resources office: "I am writing to confirm that I accept the internship offer and will begin on Monday, June 8." Nothing in the first version is a mistake. It is the right register for a friend, and the third version would be strange sent to one. Register is the level of formality and the set of word choices a writer picks to fit the reader and the occasion.

Registers differ in predictable ways. Informal writing uses contractions, sentence fragments, slang, first names and whatever spelling the keyboard gives. Formal writing spells everything out, uses complete sentences, avoids slang, uses titles and last names until invited otherwise, and follows Standard English closely. In between sits most of college and work writing: complete sentences and standard usage, but a plain, human tone, with contractions allowed in many settings. The mistake students make most is not writing too casually. It is swinging so far toward formal that the writing goes stiff: "I am reaching out to inquire as to whether" instead of "I am writing to ask whether."

Most people already switch registers all day, between a coach, a grandparent and a group chat, without thinking about it. Linguists call the deliberate version of this code-switching, and it is a form of skill, not a loss of self. The trick in writing is to notice the switch and control it. Before you write anything that matters, name the reader and the room. Then choose three things on purpose: the greeting, the level of contractions and slang, and the closing. Get those three right and the rest of the register usually follows.

One warning about the middle register. Plain does not mean careless. "I’m writing to ask whether the position is still open" is plain and correct. "im writing to ask if the position is still open" is plain and, to a hiring manager, alarming. The capital I and the apostrophe cost nothing. They tell the reader that the plainness is a choice.

Teachers, professors and managers get more email than they can read, and they sort it fast. The subject line is where the sorting happens. "Question" gets opened last. "Request to make up the Oct. 3 lab, Period 4" gets opened first and answered from memory. Make the subject line say what the email is about and, if possible, what you need. Then greet the reader by the name they use professionally: "Dear Ms. Okafor," or, once they have signed an email to you with a first name, "Hi Adaeze," is acceptable in most American workplaces.

The body should begin with the point. A common shape: one sentence that says who you are if the reader might not know, one sentence with the request or the news, then the details the reader needs to act, then thanks. Put the request near the top, not buried in paragraph three. Keep paragraphs short; on a phone, a six-line paragraph looks like a wall. If you are asking for something, make it easy to say yes: propose two times instead of asking "when works for you?" and attach what you say you attached, before you hit send.

Close with a sign-off that fits the register ("Thank you," "Best," "Sincerely,") and your full name. Add a class period or a job title if the reader may not place you. Then reread the whole thing once for tone. Email has no face and no voice, so a sentence that sounds direct in your head can sound angry on a screen. "I still have not received the form" reads as a complaint; "Could you let me know when the form is available?" asks the same thing and keeps the door open. That is tone, the attitude your words carry, and in email it is almost entirely made of word choice.

A few conventions that experienced people notice: one topic per email; reply within a day even if only to say when you will answer fully; never write in all capitals; never send an email you wrote angry without sleeping on it; and when you email a teacher or supervisor, remember that it can be forwarded, printed and read by someone you did not intend. Write what you would be comfortable seeing on a bulletin board.

A cover letter is not a summary of your résumé. It is an argument, usually three or four paragraphs long, that a specific person should want you for a specific job. The first paragraph names the job and where you saw it and states, in one sentence, why you fit. The middle paragraph or two give evidence: not "I am hardworking" but "Last summer I framed nine houses with my uncle’s crew, and I was the one who checked every measurement twice." The final paragraph asks for the interview, thanks the reader and says how to reach you. That is the whole form. Its power comes from specifics.

The conventions of the letter are fixed and are worth learning once. It is addressed to a named person when a name can be found; "Dear Hiring Manager" is the fallback, never "To whom it may concern." The register is formal: complete sentences, no slang, no contractions or very few, no jokes. It fits on one page. It uses the company’s name and the job’s title exactly as posted. It does not repeat the résumé line by line; it chooses the two or three things that matter for this job and explains them. And it is written fresh for each employer, because readers can smell a form letter in the first line.

Application forms have their own conventions. Fill every field, even the ones that seem redundant; a blank looks like carelessness. Use the same spelling of your name everywhere. Write in complete sentences where a box asks for sentences, and in short phrases where it asks for a list. Give an email address that is a version of your name, not a joke you made in seventh grade. And proofread the form the way you would a letter, because it is read by the same person.

Marcus’s letter failed on one word, and that is the last convention: a cover letter is judged more strictly than almost anything else you will write, because its whole purpose is to show what you are like when you are trying your hardest. Read it aloud. Read it backward, sentence by sentence, so that your eye stops sliding. Have someone else read it. Then wait an hour and read it once more. A letter with zero errors is not a sign of genius. It is a sign of care, and care is what the reader is hiring.

Read this paragraph from a company’s proposal, written for this lesson with its errors left in. "Our team is proud of it’s record this year. There were three project’s finished ahead of schedule, and the client’s said they were more satisfied then last year. Each of the managers have signed off. We hope you will choose us for you’re next project, its the right move." Four sentences, seven errors. A reader who catches even two of them stops trusting the numbers in the rest of the proposal. That is what credibility means: the reader’s willingness to believe you, and it is spent one small error at a time.

Four of the seven are apostrophe errors, and apostrophes cause more trouble than any other mark. The apostrophe does two jobs: it shows possession (the client’s office) and it marks missing letters in a contraction (it’s for it is). It never makes a plural. "Three projects" and "the clients" take no apostrophe. The test for its and it’s is to say "it is" out loud in the sentence: "proud of it is record" fails, so the word is its. The same test works for you’re (you are), they’re (they are) and who’s (who is).

The homophones come next: then and than, there, their and they’re, to, too and two, affect and effect, loose and lose. Than compares (more satisfied than last year); then tells time. "Could of" is not English; the phrase is could have, which sounds like could’ve in speech. Agreement errors hide when a phrase comes between the subject and the verb: "Each of the managers have signed" should be "has," because the subject is each, not managers. Cover the phrase between subject and verb and read what is left.

Here is the same paragraph repaired. "Our team is proud of its record this year. Three projects finished ahead of schedule, and the clients said they were more satisfied than last year. Each of the managers has signed off. We hope you will choose us for your next project; it’s the right move." Nothing about the content changed. Everything about the writer changed.

The essay is due at midnight and it is 11:40. Or the form must be submitted before the office closes. Editing under pressure is a skill of its own, and it is mostly a matter of order. Most people, given ten minutes, read from the top and fix whatever they happen to notice. That catches the errors in the first paragraph and almost none in the last. A better plan is to make several fast passes, each one looking for one thing, so your eye does not have to hold everything at once.

Pass one, three minutes: meaning. Read only the first sentence of every paragraph. Does the piece still make the argument you meant, in the order you meant? Fix any paragraph whose first sentence does not match its job. Pass two, three minutes: your own error list. Every writer has three or four errors they make over and over; yours might be its/it’s, run-on sentences and dropped words. Keep the list in your notes and search for those errors only. A word processor’s find function can hunt for "it’s" and " then " in seconds.

Pass three, two minutes: the mechanical checks that do not need judgment. Names spelled the same everywhere. Titles marked consistently. Every quotation with a citation. Every citation in the works cited. Numbers that match between the text and any table. The spell-checker run once, with each flag actually read, since it will not catch a correct word in the wrong place. Pass four, two minutes: read the last two paragraphs aloud, slowly, because that is where tired writers leave the most mistakes. Then stop.

Under real pressure, the last skill is knowing what to skip. A sentence that is clumsy but clear can stay. A sentence whose meaning a reader could miss cannot. When you must choose between polishing a phrase and checking whether your citation page matches your quotations, check the citations; the stakes are higher. Editing is triage. Fix what would cost you the most, in the order it would cost you, and let the rest wait for a draft you have time for.

You are writing a lab report and you cannot remember whether it is "comprised of" or "composed of," whether "data" takes "is" or "are," and whether the abbreviation for milliliters takes a period. Three questions, three different tools. Guessing is the fourth option, and it is the one most students take. Learning which reference answers which kind of question takes an hour and pays off for life.

For the meaning, spelling and standard forms of a word, the tool is a dictionary, and for American writers the one most publishers use is Merriam-Webster, which is free online. Its entries also carry usage notes on disputed words; look up "comprise" and you will find the whole argument summarized in a paragraph. For format questions, such as how to abbreviate units, how to cite or when to spell out numbers, the tool is your style guide: MLA for most English classes, APA for psychology and the sciences, Chicago for books, AP for journalism. Most school libraries have them, and the guides’ own websites answer common questions for free.

For a genuine dispute, when the dictionary says "some object" and you need to know how much they object, the tool is a usage guide, a book organized by the disputed words. Garner’s Modern English Usage and Merriam-Webster’s Dictionary of English Usage are the two most respected American ones, and they often disagree with each other, which is itself informative. The last tool is real evidence: a corpus, a large searchable collection of actual published writing. The Corpus of Contemporary American English, built by a linguist at Brigham Young University and free online, lets you see how often "the data is" appears in academic writing versus magazines. That is the descriptive view made practical.

The order matters. Dictionary, then style guide, then usage guide, then corpus. Stop as soon as you have an answer that satisfies your reader; most questions end at the first or second step. And write down what you decided in your style sheet so that you never look it up twice for the same paper. A writer who knows where to look is never stuck for more than two minutes.

Chicago speaks in many Englishes. A grandmother on the South Side may say "She be working late," using a form that African American English uses to mark a habit, something that happens regularly, which Standard English cannot say in a single verb. A student in Pilsen may say "I have twelve years" the first month after arriving from Mexico, carrying the Spanish way of stating age into English. A teenager on the Northwest Side says "gym shoes" where a New Yorker says "sneakers." Each of these is a dialect or variety of English: a full system with its own rules, sounds and words, shared by a community.

Linguists established decades ago that nonstandard varieties are not broken Standard English. African American English, sometimes called African American Vernacular English, has consistent grammar. "She be working" and "She working" mean different things, habitual and right now, and a speaker never confuses them. That grammar has been studied in universities since the 1960s and is the subject of hundreds of books. Calling a variety "bad English" is a social judgment, not a linguistic one, in exactly the way that calling one accent "no accent" is. Everyone has an accent. Everyone speaks a dialect.

None of this makes Standard English unnecessary. It is the variety of the classroom, the courtroom, the cover letter and most published writing, and a student who cannot produce it on demand is shut out of rooms they deserve to enter. The point is what kind of thing it is. Standard English is a register and a variety, not the language itself, and learning it is addition, not correction. A student who speaks African American English at home and writes Standard English in a lab report is doing what a bilingual person does. That is more skill, not less.

For the writer, two practical rules follow. First, in a setting that expects Standard English, use it, and use it well; the reader is not wrong to expect it. Second, never treat another person’s variety as a sign of intelligence or effort. In dialogue, in a quotation or in a profile, render a person’s speech accurately and respectfully, and do not "correct" a quotation into a dialect the speaker did not use. A writer who understands variety is harder to fool and kinder on the page.

A reporter spells a source’s name wrong, and the source never trusts the newspaper again. A form lists a student as "Jonathan" when he has gone by "Jon" his whole life. A letter opens "Dear Sirs" to an office run by three women. None of these is a grammar error, yet each one costs the writer more credibility than a comma splice, because each says the writer did not look. Respect in usage starts with accuracy about people: their names, spelled as they spell them; their titles, as they hold them; their pronouns, as they state them.

Names for groups follow the same principle. Use the term a group uses for itself, and know that these terms change. Most American style guides now capitalize Black when referring to people; they are divided on White. Native American, American Indian and Indigenous are all in use, and the most respectful choice is often the specific nation, such as Potawatomi, whose people lived where Chicago now stands. Latino, Latina, Hispanic and the newer Latinx are used by different people for different reasons; the AP Stylebook notes that Latinx is not widely used by the people it describes. When in doubt, ask, or follow the usage of the community’s own institutions.

Person-first language ("a student with a disability") was the standard for decades; some communities, including many autistic and Deaf people, prefer identity-first language ("an autistic student"). Neither is wrong. The respectful move is to use what the person or community prefers, and, when writing about individuals, to mention a disability, a religion or an origin only when it is relevant to the point. That last rule, relevance, does most of the work. A sentence that mentions a person’s background when it has nothing to do with the story tells the reader more about the writer than about the subject.

Finally, the generic masculine, using he and man to mean everyone, was standard until the 1970s and is now avoided by every major guide. Write "a nurse should wash her hands" only if the nurse is a specific woman; otherwise recast in the plural ("nurses should wash their hands"), use singular they or repeat the noun. None of this is about fear of offending. It is the same discipline as every other lesson in this unit: knowing who the reader is, and choosing the words that let the reader see the subject clearly instead of seeing the writer’s assumptions.
