Common mistakes
- Wrong: Yo concluye la reunión a las cinco. — Right: Yo concluyo la reunión a las cinco. — The person matters: concluye is the él/ella/Ud. form, while the yo form is concluyo. Using the third-person form with yo is one of the most common beginner errors.
- Wrong: Yo concluo el informe con una idea clara. — Right: Yo concluyo el informe con una idea clara. — Concluir is a -uir verb: the stem vowel i becomes y before a vowel ending, so the present is concluyo and concluye, and the gerund is concluyendo. The form concluyo follows that pattern, not the plain stem plus -o.
- Wrong: Treating concluir and terminar as identical in every context. — Right: Concluir means to conclude, while terminar means to finish. — They overlap, but each has uses the other does not: concluir fits sentences such as Concluyo la reunión a las cinco, while terminar belongs in a different sentence. Check the meaning you want before choosing.
- Wrong: Yo soy concluido el informe con una idea clara. — Right: Yo he concluido el informe con una idea clara. — Spanish perfect tenses use haber, not ser: he concluido, has concluido, ha concluido. Ser plus the participle makes a passive, not a perfect tense.
- Wrong: De niño, yo concluí sus estudios en junio todos los días. — Right: De niño, yo concluía sus estudios en junio todos los días. — For a repeated habit in the past, use the imperfect (concluía), not the preterite. The preterite (concluí) is for one finished action.

Frequently asked questions
What does concluir mean in English?
Concluir means to conclude. It is used in everyday situations such as Concluyo la reunión a las cinco. The exact English wording depends on the context, but the core meaning stays the same across the tenses.
Is concluir regular or irregular?
Concluir is a spelling-change verb: it is a -uir verb: the stem vowel i becomes y before a vowel ending, so the present is concluyo and concluye, and the gerund is concluyendo. The endings are regular, so once you know the pattern you can produce every form on this page, including concluyo in the present and concluí in the preterite.
What is the difference between concluir and terminar?
Concluir means to conclude, while terminar means to finish. They are easy to confuse because they appear in similar situations, but they are not interchangeable: use concluir when you mean to conclude, as in Concluyo la reunión a las cinco, and use terminar for to finish. When in doubt, check the object of the sentence — it usually shows which verb fits.
How do I say “I conclude” in the past?
It depends on the kind of past. For one finished action, use the preterite: yo concluí el informe con una idea clara. For a repeated habit or background in the past, use the imperfect: yo concluía sus estudios en junio. For something that has just happened, use the present perfect: yo he concluido el informe con una idea clara.
