Dormir Present Practice

Dormir (to sleep) in the present: 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

Dormir is a textbook o→ue stem-changer in the present: duermo, duermes, duerme, duermen. Only nosotros and dormís-style vosotros keep the original o of the stem (dormimos, dormís), while the endings themselves are the regular -ir set.

The trap runs in both directions: beginners either forget the change entirely (dormo) or push it into the nosotros form (duermimos). Remember the boot: the ue appears everywhere except nosotros and vosotros.
