¡Hola! I am Studyfin, your Spanish tutor. Let's master the two ways to talk about the past in Spanish!
In Spanish, we have two main past tenses: the preterite and the imperfect. We use the preterite for completed actions that happened once. We use the imperfect for ongoing habits or descriptions in the past.

Think of the preterite as a single pop! It is a specific event with a clear start and finish, like 'yo corrí' (I ran — yo koh-REE). Let's see how a single action cuts through time.
Now, think of the imperfect as a wavy, continuous line. It shows habits, background settings, or age, like 'yo corría' (I used to run — yo koh-REE-ah). It does not have a clear start or end.
To analyze which tense to use, look for clues. If a sentence tells you exactly how many times an action happened, choose the preterite. If it describes weather, time, or an ongoing routine, choose the imperfect.
Analyze the following sentence and decide which verb tense is correct: 'Ayer, yo (hablar / hablaba) con mi abuela' (Yesterday, I talked to my grandmother).
- Identify the time frame clue in the sentence: 'Ayer' (yesterday — ah-YEHR).
- Analyze the nature of the action. Talking to your grandmother yesterday is a completed, one-time event.
- Recall the rule: Completed, one-time events use the preterite tense.
- Select the preterite conjugation of the verb 'hablar' (to speak) for 'yo' (I), which is 'hablé' (I spoke — ah-BLAY).
- Justify the final sentence: 'Ayer, yo hablé con mi abuela' is correct because the action happened at a specific, completed time in the past.
