Pretérito vs. Imperfecto (Preterite vs. Imperfect): Key Differences

Learning Objectives Distinguish between the primary uses of the preterite and imperfect tenses to narrate past events. Conjugate regular -ar, -er, and -ir verbs in both the preterite and imperfect tenses. Identify and correctly use common irregular verbs in both tenses (e.g., ser, ir, ver, dar).

Construct narrative paragraphs that effectively combine the preterite and imperfect to set a scene and describe a sequence of events. Explain how certain verbs (e.g., querer, saber, conocer) change meaning depending on their use in the preterite or imperfect.

When one action was in progress and another action suddenly happened, the ongoing action takes the imperfect, and the interrupting action takes the preterite. The word 'cuando' (when) often connects them. Verbs with Meaning Changes Certain verbs change their nuance based on the t...
