There are only two sets of endings for regular imperfect verbs in Spanish, one for -ar verbs and one for both -er and -ir verbs. To conjugate a regular verb in the imperfect tense in Spanish, simply remove the infinitive ending ( -ar, -er, or -ir) and add the imperfect ending that matches the subject.
As we learned in our previous lesson about the Preterit Tense, we have two forms of the past tense in Spanish: The Preterit Tense and The Imperfect Tense. We have covered the Preterit Tense and all of its irregulars so now it’s time to learn about the Imperfect Tense!
The Imperfect Tense in Spanish is a tense used for actions that are recurring, that do not have a specific start or end, or that were happening when something else interrupted (Preterit Tense). Think about this tense as being something that happened “over and over” while the Preterit Tense was “one and done”.
Let’s look at a few examples in English. The bold parts are the verbs that will be conjugated in the Imperfect Tense:
I used to watch Barney as a child.
When he was a kid, he always traveled to Texas.
We were watching TV when the power suddenly went out!
How to conjugate in the Imperfect Tense
The endings for -AR verbs in the Imperfect Tense
| -aba | -ábamos |
| -abas | -abais |
| -aba | -aban |
NOTE: The endings for the yo and él/ella/usted forms are the same. This means the only way to tell the difference is based on the context of the sentence in which it’s used.
The endings for -ER and -IR verbs in the Imperfect Tense
| -ía | -íamos |
| -ías | -íais |
| -ía | -ían |
NOTE: The endings for the yo and él/ella/usted forms are the same. This means the only way to tell the difference is based on the context of the sentence in which it’s used. ALSO, the first “i” in each of these endings must have an accent (í).
