Imperfect Tense (Pretérito Imperfecto): Formation and Use

Welcome to our lesson on the Pretérito Imperfecto, or the Imperfect Tense!

This past tense is your key to painting vivid pictures of the past. While other past tenses focus on completed actions, the Imperfect describes ongoing situations, repeated habits, and the background scenery of a story. Think of it as setting the stage. In English, it often translates to "was/were + verb-ing" or "used to + verb".

✅ How to Form the Imperfect Tense

The great news is that the Imperfect is one of the easiest tenses to conjugate in Spanish!

There are only two sets of endings for regular verbs:

1️⃣ For -AR verbs (like hablar - to speak):
Remove the -ar ending and add these endings:

🔹 yo hablaba
🔹 tú hablabas
🔹 él/ella/usted hablaba
🔹 nosotros/as hablábamos (Note the accent on the 'a'!)
🔹 vosotros/as hablabais
🔹 ellos/ellas/ustedes hablaban

2️⃣ For -ER and -IR verbs (like comer - to eat, and vivir - to live):
Both verb groups share the same endings! Remove the -er or -ir and add:

🔹 yo comía / vivía
🔹 tú comías / vivías
🔹 él/ella/usted comía / vivía
🔹 nosotros/as comíamos / vivíamos
🔹 vosotros/as comíais / vivíais
🔹 ellos/ellas/ustedes comían / vivían

Notice that all these endings have an accent on the 'í'.
