Common mistakes

Forgetting the accent in the preterite

The yo preterite form is redondeé, with an accent on the stressed vowel. Writing it without the accent — redondee — 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 redondear.

Mixing up present and preterite nosotros

For redondear, the nosotros form is the same in the present and the preterite: redondeamos. 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 redondeado el precio. English speakers sometimes reach for soy because English uses to be in some passives, but soy redondeado is not the present perfect of redondear — it is a passive construction with a different meaning.

Confusing redondear with reducir

redondear and reducir 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 redondear — round — the sentence needs redondear; if it needs the meaning of reducir, use that verb instead.

Using the indicative after "espero que"

After espero que (I hope that), Spanish needs the subjunctive: Espero que yo redondee el precio. Using the indicative — Espero que yo redondeo — is one of the most frequent learner errors with redondear. Whenever the main clause expresses a wish, doubt or emotion, switch to the subjunctive.
