Purpose
By the end of this lesson, you will be able to conjugate regular and the most common irregular verbs in the preterite tense.
Lesson Explanation
The preterite expresses a completed, one-time past action. Regular -ar verbs: hablé, hablaste, habló, hablamos, hablasteis, hablaron. Regular -er/-ir verbs share identical endings: comí, comiste, comió, comimos, comisteis, comieron.
A genuinely important detail: the nosotros form of regular -ar and -ir verbs is identical in the preterite and present tense (hablamos serves both) — only context distinguishes them.
A significant group of extremely common verbs is irregular, often changing the stem AND dropping the usual accent marks: ser/ir (identical forms, distinguished only by context): fui, fuiste, fue, fuimos, fuisteis, fueron. Tener: tuve, tuviste, tuvo, tuvimos, tuvisteis, tuvieron. Estar: estuve, estuviste, estuvo, estuvimos, estuvisteis, estuvieron. Hacer: hice, hiciste, hizo, hicimos, hicisteis, hicieron (note hizo uses “z” instead of “c” to preserve the correct sound).
A genuinely distinctive irregular group: verbs like pedir and sentir that are stem-changing in the present (Part 1, Lesson 4) show a DIFFERENT stem change in the preterite, but only in the él/ella and ellos/ellas forms: pedir → pedí, pediste, pidió, pedimos, pedisteis, pidieron (e→i only in the third-person forms, unlike the present tense’s broader e→i pattern). This preterite-specific stem change is a genuinely separate phenomenon from the present-tense stem change, despite looking similar, and must be learned as its own pattern.
