In K–2 you pulled a word apart into sounds. Now you pull it apart into meanings. A root carries what the word is about, a prefix goes on the front and changes it, and a suffix goes on the end and usually changes the word's job. Learn twelve of these pieces and you can work out the meaning of words nobody has ever taught you — which is the whole point. Five tabs — cards for the pieces, hints with the prefix and suffix chart, a quiz that asks you to build and break words, and a workshop where you sort real prefixes from lookalikes, build a word in order, label the parts and say why word parts beat memorizing.
Start with the root. happy carries the meaning — everything this word is about is already in here.
The ROOT carries the meaning. A PREFIX on the front changes that meaning. A SUFFIX on the end changes the word’s JOB. Find the root first — twelve of these parts will unlock hundreds of words you were never taught.
Two things people get wrong
⚠️People often think…
It starts with re–, so re– is the prefix.
Only if a real word part is left behind. Take re– off rebuild and build is left, so it is a prefix. Take re– off red and you are left with d, which is nothing — red just happens to start with those letters. Same test for pretty, dish and uncle.
Take it off. If nothing real is left, it was not a prefix.
⚠️People often think…
un– always means “not”, so untie means not tie.
un– has two jobs. On a word that describes — happy, kind, fair — it means not. On an action you can reverse — tie, lock, pack — it means undo it. The ROOT tells you which one you have, so read the whole word before you decide.
The root decides which job the prefix is doing.
Root, then front, then end
1Watch one
Work out what transportable means, without being told.
Find the root first: port, which means carry.
Check the front: trans–, which means across.
Check the end: –able, which means it can be done.
Put the three together: something that can be carried across — something you can move from place to place.
2Do one with me
Give the meaning of each part.
re– means
mis– means
port means
💬One sentence, then you move on
Why is learning twelve word parts worth more than learning twelve words?
3Try one
Which part of a word should you look for FIRST? Write one word.
I want a hint first
It is the part that is left when you take the front and the end away.
Where this goes
Where this lives
Every science and social studies word you meet this year is built from parts like these — they came into English from Latin, which is why transport and transporte are relatives.
What this feeds
Next room: when the parts only get you close, the sentence finishes the job.
Find one long word near you and say its root out loud.
One card at a time — tap “Show me” to check yourself, then Next. Start at Foundation; when those feel easy, climb.
Helpful Hints
🧭 The unit in one line
Find the root first — it carries the meaning → check the front for a prefix that changes it → check the end for a suffix that changes the word's job → then put the three answers together.
Root = what it is about. Prefix = changes it. Suffix = changes its job.
🔑 The one idea
Twelve word parts will unlock hundreds of words. That is why this is worth more than learning hundreds of words one at a time — the parts keep working on words you have never seen.
⚠️ Traps to avoid
un- does not always mean “not.” Unhappy means not happy, but untie means the opposite of tie — you undo it. Look at what the whole word does.
Letters that look like a prefix often are not one. Red and ready start with r-e and have no prefix, because d and ady are not roots.
Take the prefix off and a real root is left. If what is left is not a word part you know, there was no prefix.
A suffix usually changes the word's JOB, not its topic. Care, careful and carefully are all about caring — but one is a thing, one describes, and one tells how.

🎯 How you will be asked
“What does the prefix in this word mean?”
“Break this word into its parts.”
“Which of these four words has a real prefix?”
“Use the parts to work out what this word you have never seen means.”
“Add a suffix so this word can be used to describe something.”
✅ Before the test, can you…
Give the meaning of un–, re–, pre–, dis– and mis–?
Say what –ful, –less, –er, –ly and –tion do to a word?
Tell a real prefix from letters that only look like one?
Break unhappiness into three parts and say what each does?
Work out a word you have never seen from its parts?

How sure did you feel?
Workshop
Work like someone who takes words apart: sort twelve words by whether the front is a real prefix, put the four checking steps in order, label the parts of unhappiness, then say why twelve parts beat a word list.
