Creer Commands Practice

Creer (to believe, to think) in the commands: 14 free exercises with an explanation after every answer, plus the full conjugation table.

IWhat to watch for

Creer forms regular commands: cree for tú, and the subjunctive for the rest — no creas, crea, creamos, crean. The affirmative tú command is spelled with a double e: cree.

In conversation the commands often carry a pronoun — créeme, believe me; no te lo creas, don't believe it — but the forms underneath are the same. On this page every answer is the plain form, and the classic trap is creamos (command) against creemos (present).
