The Pretérito Imperfecto is one of the past tenses in Spanish, used to describe habitual actions, ongoing events, and situations in the past. It provides context or background without indicating when the action specifically started or ended. Below, we’ll explore its use, conjugation for regular and irregular verbs, and common expressions.

When Do We Use the Pretérito Imperfecto?

1. Describing habitual or repeated actions in the past
   • Example: Cuando era niño, jugaba al fútbol todos los días.
     (When I was a child, I played soccer every day.)
2. Setting the scene or providing background information
   • Example: Hacía frío y nevaba cuando llegué a casa.
     (It was cold, and it was snowing when I arrived home.)
3. Describing mental states, emotions, or physical conditions in the past
   • Example: Estaba cansado después del trabajo.
     (I was tired after work.)
4. Actions that were in progress in the past (without focusing on their start or end)
   • Example: Leía un libro mientras ella cocinaba.
     (I was reading a book while she was cooking.)
5. Telling time and age in the past
   • Example: Eran las cinco de la tarde.
     (It was five in the afternoon.)
     Tenía veinte años en ese momento.
     (I was twenty years old at that time.)
