Spanish Preterite Tense Practice Generator

A learner writes "comía pizza anoche" meaning to say they ate pizza last night, and lands on the imperfect instead because the action happened in the past and past felt like past. Anoche marks one finished event, not a repeated habit, and Spanish keeps a separate tense for exactly that job. This generator drills the preterite by itself, away from the imperfect entirely, so the ending gets solid before the two tenses start competing for the same sentence.

The verb is [VERB?] (a specific infinitive, or leave this blank and I'll choose one common enough to matter at [CEFR_LEVEL]).

CEFR level is [CEFR_LEVEL:select:A1 (beginner),A2 (elementary),B1 (intermediate),B2 (upper intermediate),C1 (advanced)].

Subject pronouns to drill are [PRONOUN_SET:select:all six subject pronouns,singular only (yo/tú/él-ella-usted),plural only (nosotros/vosotros/ellos-ellas-ustedes),yo and él/ella/usted only].

Build [ITEM_COUNT:number:6-25] practice sentences.

Anchor every sentence to a specific finished moment, ayer, anoche, el año pasado, la semana pasada, so the single-completed-action meaning stays attached to the form and doesn't drift into something ongoing. For regular verbs, -ar verbs take -é, -aste, -ó, -amos, -asteis, -aron, while -er and -ir verbs share -í, -iste, -ió, -imos, -isteis, -ieron. Mark the accented syllables clearly, since the accent on the yo and él/ella/usted forms is what separates them from other conjugations, not just spelling decoration. Flag one thing explicitly if [VERB] is -ar or -ir: the nosotros form of the preterite is spelled exactly like the present tense nosotros form, hablamos and vivimos work in both tenses, so a sentence using that pronoun needs the time marker doing the real work of showing which tense it is.

If [VERB] happens to be one of the irregular preterite verbs, tener, decir, hacer, and similar verbs that build their own irregular stem and drop the accented endings entirely, note that plainly and keep this set to a verb from that list only when it was explicitly requested. That group of verbs is dense enough to need its own dedicated drilling, not a handful of items mixed into a regular-pattern set where the irregularity gets lost.

Close by writing one sentence pair that shows the same verb used with two different time markers, so the pattern of marker-plus-preterite reads as one unit instead of two separate things to remember.
