Spanish imperfect past tense: Formation, Use and Examples

The preterite imperfect, also known as "imperfecto" or "pretérito imperfecto del indicativo", is another of the most commonly used verb tenses in Spanish to refer to past actions. Unlike the simple past (pretérito indefinido) which denotes actions completed in the past, the preterite imperfect is used to express actions that occurred habitually, repeatedly, enduringly or were in progress at a specific time in the past.


The Spanish imperfect tense at a glance

The preterite imperfect is used in various situations, such as describing habitual actions in the past, expressing the time in which an action occurred simultaneously with another in the past, narrating situations in the past, describing physical or mental characteristics in the past, among others. It is one of the most used verb tenses in narrations and descriptions in Spanish.

Formation of the Spanish Imperfect past tense

The formation of the imperfect is quite regular in Spanish for most verbs. The ending of verbs in -ar, -er and -ir is the same for most personal pronouns. Here is the imperfect conjugation for three regular verbs: "hablar" (verb -ar), "comer" (verb -er) and "vivir" (verb -ir):

Uses of the imperfect tense in Spanish:

1. Habits or repetitive actions in the past: The imperfect is used to describe actions that occurred frequently or repeatedly in the past. For example:

"Every day I walked to the park."

2. Description of the setting or environment in the past: used to state the setting or situation at a specific time in the past. For example:

3. Ages and times in the past: The imperfect is also used to express someone's age or time in the past. For example:

Differences between the preterit and the imperfect tense

It is common for students of Spanish to find it difficult to differentiate between the preterite and the imperfect, as both are past tenses. The main distinction lies in how the actions are focused:

  • The preterite is used to express punctual, specific and completed actions in the past. It is used to narrate concrete events with a clear beginning and end.
  • The imperfect, on the other hand, is used to describe actions that were habitual, continuous or occurred without a definite end point. It focuses on the development or duration of the action rather than its completion.

For example, consider these two sentences:

  • Pretérito: "Yesterday I went to the movies". In this case, the action "ir al cine" is specific and punctual, with a clear beginning (ayer) and an end (cuando llegué al cine).
  • Imperfect: "When I was a kid, I went to the movies every Saturday". Here, the imperfect is used to express a habitual and repetitive action in the past, without a specific end point.
