The Preterit

Regular Verbs

Like most Spanish tenses, the regular verbs are conjugated by changing the endings on the vern stem. The verb stem is the same as other tenses. The ending changes based on the table below.

Verb Endings
-ar-er, -ir
yo
-aste-iste
él, ella, usted-ió
nosotros/as-amos-imos
vosotros/as-asteis-isteis
ellos, ellas, ustedes-aron-ieron

Note: For the plural first person, the conjugation is the same as the present tense. This is great for memorizing conjugations. It however leaves the speaker/listener to figure out the tense using the context of the sentence.

Verbs with Changes in Spelling

Two general rules exist for spelling changes in the preterit. These changes create modifications to the typical regular conjugation shown above.

  1. Verbs ending in -car, -gar, -guar, -zar are changed only in the first person singular. Below are some examples.

-ir Verbs with Spelling Changes

Stem-changing -ir verbs (e to ie, e to i, o to u) in the present tense change their corresponding vowel of the stem in the third person singular and plural conjugations.

The changes happen in two different ways, e to i and o to u.
