Spanish Grammar Test: Past Imperfect Tense

Past Imperfect Tense of Ser and Ir

Useful Grammar

There are only two verbs of importance* which are irregular in the past imperfect tense: ser and ir. Although the form of these verbs changes considerably in the past imperfect tense, their endings remain regular. Thus, their conjugation is not difficult to remember.

* The verb ver is also irregular in the past imperfect tense, although only slightly so. The letter e is simply added to the stem.

Since ver is not widely used in this tense, special consideration is not given to it here; attention, instead, is concentrated on ser and ir. Practice sentences, however, with ver will appear in future exercises.
