Spanish Imperfect
The imperfect is the cleanest tense to conjugate in Spanish. Two endings sets, three irregular verbs, and a small set of time markers that trigger it.
Regular endings
-ar verbs ():
| Person | Ending | hablar |
|---|---|---|
| yo | -aba | |
| -abas | ||
| / / | -aba | |
| -ábamos | ||
| -abais | ||
| / / | -aban |
-er and - verbs (, ) - they share the same endings:
| Person | Ending | comer | vivir |
|---|---|---|---|
| yo | -ía | ||
| -ías | |||
| / / | -ía | ||
| -íamos | |||
| -íais | |||
| / / | -ían |
Two things to flag: the yo and // forms are identical (hablaba, comía, vivía). Spanish disambiguates with context or by reinstating the subject pronoun when needed. And the forms take a written accent (hablábamos, comíamos, vivíamos) - mandatory.
The only three irregulars
In the entire imperfect tense, there are exactly three irregular verbs.
(to be):
| Person | ser |
|---|---|
| yo | |
| / / | |
| / / |
(to go):
| Person | ir |
|---|---|
| yo | |
| / / | |
| / / |
(to see) - slightly irregular, keeping the e of the infinitive:
| Person | ver |
|---|---|
| yo | |
| / / | |
| / / |
That's the entire irregular set. Every other verb in Spanish - including stem-changers and famously irregular verbs like tener, hacer, decir, poder, querer - is regular in the imperfect.
When to use it
Three core uses.
1. past actions ("I used to", "I would"):
- . (As a child I used to play football.)
- . (Every Sunday we would eat at my grandmother's house.)
- Madrid. (I used to live in Madrid.)
2. Ongoing past actions ("I was X-ing"):
- , . (While I was studying, my sister was cooking.)
- me , . (When you called me, I was sleeping.)
3. Background description / setting the scene:
- y . (The house was big and had a garden.)
- y . (It was cold and it was raining.)
- María . (Maria was twenty years old.)
Time markers that trigger the imperfect
- (always)
- / / (every day / week / year)
- (normally)
- a (often)
- (while)
- / / (when I was a child / small / young)
- / (as a child / as a young person)
If one of these markers shows up, you're almost certainly looking at imperfect, not preterite.
Worked examples
- , . (When I was a child, I lived in London.)
- . (My father worked at a bank.)
- . (We spoke Spanish at home.)
- a . (Every summer we used to go to the beach.)
- , . (While I was reading, the phone rang. - imperfect for the ongoing, preterite for the interrupting event)
- . (It was three in the afternoon.)
- a . (I used to see my grandfather every weekend.)
Common mistakes English speakers make
Forgetting the written accent on the nosotros forms: is wrong, it's . Treating "I was sleeping" as a single English form and translating it into Spanish with when would do. Both are grammatical, but the simple imperfect is the unmarked default. And forgetting that ser, ir and ver are the only three irregulars - learners often try to invent irregular forms for tener ( is regular!) or hacer ( is regular).
