Dormir Imperfect Practice

Dormir (to sleep) in the imperfect: 14 free exercises with an explanation after every answer, plus the full conjugation table.

14 exercisesStem-changing o→ueA1 – A2 level
IWhat to watch for

Good news for dormir in the imperfect: it is completely regular. The o→ue and o→u changes that trip you up elsewhere disappear here, giving dormía, dormías, dormía, dormíamos, dormíais, dormían — the plain -ir imperfect endings on the full stem.

The imperfect describes what used to happen: habits, repeated nights, and background situations. Time cues like siempre, de bebé, cuando era niño and todas las noches point straight to it. The only thing to watch is the written accent on every -ía ending.
