The imperfect tense, in the classical grammar of several Indo-European languages, denotes a past tense with imperfective aspect. It corresponds to the English past-continuous tense.

In Spanish, the imperfect is a past tense. Its uses include representing:

• An action that was going on at the same time as another action
• An action that was going on when another action occurred
• A habitual action in the past.
• A description of a mental, emotional, or physical condition
• The time or date in the past

Notes:

• The yo and el/ella/usted forms are the same for verbs ending in ar, er, and ir.
• There are only three irregular verbs in the imperfect tense: ir, ser, and ver.
