One past tense, two sets of endings, and only three irregular verbs in the whole language. Study Cards teach the forms, Helpful Hints hand you the chart and the traps, the Practice Quiz checks you in three tiers, and the Workshop puts you inside a story where the imperfect holds the scene still and the preterite moves the plot.
The long band is a scene that was already going on. Nothing has happened yet.
Each job has its own past tense. The band is the imperfect: it holds the scene. The arrow is the preterite: one finished event. Yo leía cuando sonó el teléfono — leía is the band, sonó is the arrow.
What people get wrong
⚠️People often think…
The preterite is for short actions and the imperfect is for long ones.
Length is not the test. Viví en Texas diez años is preterite, and it covers ten years. The question is whether the sentence frames the action as finished. Framed as finished, you get the preterite. Left open as the scene, you get the imperfect.
Ask finished or not, never short or long.
⚠️People often think…
Tener and hacer are irregular verbs, so they are irregular in the imperfect too.
Only three verbs are irregular in this tense: ir, ser and ver. Tener is tenía, hacer is hacía, decir is decía, estar is estaba, poder is podía. The verbs that fight you in the preterite line up here.
Ir, ser, ver. Every other verb takes the endings.
⚠️People often think…
Había becomes habían when there is more than one thing.
Había has no plural. One word covers there was and there were. Había un libro and Había muchos libros are both correct.
Never habían. Había does both jobs alone.
⚠️People often think…
The accent on comía is decoration, so the word is right without it.
The accent is part of the spelling. Every -er and -ir form carries it on the í: comía, vivías, veíamos. In -ar verbs only the nosotros form takes one: hablábamos.
-ía always. In -ar only hablábamos.
The band and the arrow
1Watch one
Yo leía cuando sonó el teléfono. Which verb is the band, and which is the arrow?
Two verbs here: leía and sonó.
The reading was already going on.
The phone rang once and ended.
Leía is the band, sonó is the arrow. ✓
2Do one with me
The band words are imperfect. Build three of them.
The imperfect of hablar in yo is
The imperfect of comer in ella is
Of ir, ser and ver, the verb that gives iba is
💬One sentence, then you move on
Why can the reading and the phone call not take the same tense?
3Try one
Mientras yo ___ (estudiar), mi hermano llegó.
I want a hint first
Mientras always marks the band — the action that was already going on. So this verb is imperfect, and estudiar is an -ar verb, so yo takes -aba.
💬Last one — then you are done here
Why does a story need two past tenses and not one?
Where this goes
Where this lives
Telling anyone about something that happened to you, in any language. The scene says where you were and how it felt. The events say what happened. With only the events it is a list, not a story.
What this feeds
Next unit is pronouns, reflexives and commands — the words that say who the story happened to, and how to tell someone to do a thing.
Name one thing that was going on yesterday, and one thing that happened once.
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
Two sets of endings (-aba and -ía) → only three irregulars (ir, ser, ver) → the imperfect paints the scene: habits, description, age, time, weather, feelings → the preterite moves the plot → put them in one sentence and you get the interruption: Yo leía cuando sonó el teléfono.
Ir, ser, ver — iba, era, veía. Three verbs. That is the whole irregular list.
🔑 The one idea
A story needs two past tenses, and each has a job. The imperfect is the camera that holds still: it shows the weather, the people, the feelings, and what used to happen again and again. The preterite is the camera that cuts: one finished action, then the next. Ask which job the verb is doing and the tense chooses itself.
⚠️ Traps to avoid
Accents are part of the spelling. Every -er and -ir form needs the í: comía, vivías, veíamos. In -ar verbs only nosotros takes one: hablábamos.
Yo and él, ella, usted are spelled the same: hablaba, comía, era, iba. Say the subject word so the reader knows who did it.
Había never becomes habían. One word covers there was and there were.
Age in the past is always the imperfect: tenía ocho años, never fui ocho años.
Mientras marks the action that was going on, so it takes the imperfect: mientras yo estudiaba, not mientras yo estudié.
Supe is not knew — it is found out. Conocí is not knew — it is met. Watch those five verbs.
The imperfect never says when the action stopped. If the sentence gives a finished moment, you probably want the preterite.

Words that tip you off to the imperfect: siempre (always), todos los días (every day), generalmente (usually), de vez en cuando (once in a while), mientras (while), cuando era niño (when I was a child). Words that tip you off to the preterite: ayer, anoche, de repente (suddenly), una vez (one time), el año pasado.
🎯 How you will be asked
“Write the six imperfect forms of hablar, comer and vivir.”
“Name the three irregular verbs and give the yo form of each.”
A sentence with a blank and a time marker — “preterite or imperfect, and why?”
“Explain why Yo leía cuando sonó el teléfono needs two different past tenses.”
“Translate supe, conocí, quiso, no quiso and pude, and say how each differs from its imperfect.”
✅ Before the test, can you…
Write both sets of endings from memory, with the accents?
Conjugate ir, ser and ver in the imperfect without looking?
Give six jobs the imperfect does — habits, description, age, time, weather, feelings?
Spot a time marker and name the tense it calls for?
Build an interruption sentence of your own with mientras or cuando?
Tell sabía from supe, conocía from conocí, and no quería from no quiso?
📚 Go to the sources
These open another website and need the internet. On the RAE dictionary, look up any verb and press Conjugar to see every form, including the imperfect. On Project Gutenberg, read the first line of Don Quijote and count the imperfects before the first preterite arrives.
Look back at anything you missed — the hint that appeared is exactly what to reread tonight.

Workshop
Work like a storyteller: build a story from scene to action, read a time marker and know the tense it calls for, tag a whole story sentence by sentence, then explain why one sentence needs two past tenses.
