There are only two sets of endings for regular preterite verbs, one for -ar verbs and one for both -er and -ir verbs. To conjugate a regular verb in the preterite tense, simply remove the infinitive ending (-ar, -er, or -ir) and add the preterite ending that matches the subject. Check out the table of regular preterite endings below.
Regular Preterite Verb Endings
Subject -ar Verbs -er and -ir Verbs
yo -é -í
tú -aste -iste
él, ella, usted -ó -ió
nosotros -amos -imos
vosotros -asteis -isteis
ellos, ellas, ustedes -aron -ieron
Keep an Eye on the Accents
Note that the first person singular (yo), third person singular (él, ella), and second person formal singular (usted) preterite forms have tildes (written accents) on the final vowel. Keep in mind that one little tilde can change both the tense and subject of a sentence. For example:
With a tilde:
Mandó una carta.
He/She sent a letter.
Without a tilde:
Mando una carta.
I send a letter.
Present and Past Nosotros
The first person plural (nosotros) endings for regular -ar and -ir verbs are the same for both the preterite and present tenses. Context clues, such as adverbs like siempre (always) and ayer (yesterday), can help you figure out if a nosotros form refers to the past or the present.
Siempre cocinamos paella los domingos.
We always cook paella on Sundays.
Ayer cocinamos paella para mi familia.
Yesterday we cooked paella for my family.
