Common mistakes

Forgetting the accent in the preterite

The yo preterite form is revolucioné, with an accent on the stressed vowel. Writing it without the accent — revolucione — is a spelling error, and in speech the stress lands in the wrong place. Preterite yo forms that end in a vowel carry that accent, so check it every time you write the preterite of revolucionar.

Mixing up present and preterite nosotros

For revolucionar, the nosotros form is the same in the present and the preterite: revolucionamos. Only the context tells you which tense is meant, so pay attention to the time words around it — cada día points to the present, ayer points to the preterite. Do not invent a different form for one of the tenses.

Using ser instead of haber in perfect tenses

Spanish perfect tenses always use haber, never ser: yo he revolucionado la industria. English speakers sometimes reach for soy because English uses to be in some passives, but soy revolucionado is not the present perfect of revolucionar — it is a passive construction with a different meaning.

Confusing revolucionar with revisar

revolucionar and revisar look similar, and learners mix them up. They are different verbs with different meanings, so check which one the sentence needs before you conjugate. If you can substitute the English meaning of revolucionar — revolutionise — the sentence needs revolucionar; if it needs the meaning of revisar, use that verb instead.

Using the indicative after "espero que"

After espero que (I hope that), Spanish needs the subjunctive: Espero que yo revolucione la industria. Using the indicative — Espero que yo revoluciono — is one of the most frequent learner errors with revolucionar. Whenever the main clause expresses a wish, doubt or emotion, switch to the subjunctive.
