Tip

Working with the preterite

The preterite describes a finished past action with a clear boundary — "ayer comí pizza" (yesterday I ate pizza). The key contrast is with the imperfect, which describes ongoing or repeated past actions without a defined endpoint. If you can substitute "used to" or "was doing" in English, you usually want the imperfect; if the action is one-and-done, you want the preterite. The irregular preterites (fui, hice, dije, tuve, vine, supe) are the highest-frequency in Spanish — front-load them.

Questions

Frequently asked questions

How do you conjugate comer in the preterite?
The preterite of comer is: yo comí, tú comiste, él/ella/usted comió, nosotros/as comimos, vosotros/as comisteis, ellos/ellas/ustedes comieron. The accents on 'comí' and 'comió' are required — they signal the preterite and shift stress to the last syllable. Every regular -er and -ir verb shares this exact ending pattern (vivir → viví, vivió; aprender → aprendí, aprendió).
Are the preterite endings the same for -er and -ir verbs?
Yes — -er and -ir verbs share identical preterite endings: -í, -iste, -ió, -imos, -isteis, -ieron. Compare comer (comí, comiste, comió, comimos, comisteis, comieron) with vivir (viví, viviste, vivió, vivimos, vivisteis, vivieron) — they differ only in spelling, not pattern. Only -ar verbs have a different preterite pattern (hablé, hablaste, habló, hablamos, hablasteis, hablaron).
When do I use 'comí' instead of 'comía'?
Use 'comí' for a specific completed meal: 'Anoche comí pizza' (Last night I ate pizza). Use 'comía' for habitual or ongoing past eating: 'De niño, comía pizza cada viernes' (As a child, I used to eat pizza every Friday). Preterite = one-time event; imperfect = habitual or descriptive.
