Common mistakes
- Wrong: Yo coexiste en paz con los vecinos. — Right: Yo coexisto en paz con los vecinos. — The person matters: coexiste is the él/ella/Ud. form, while the yo form is coexisto. Using the third-person form with yo is one of the most common beginner errors.
- Wrong: Ayer yo coexisto con otras religiones. — Right: Ayer yo coexistí con otras religiones. — The present and the preterite are different tenses: coexisto is happening now, while coexistí is a finished action in the past. Use the preterite with ayer.
- Wrong: Treating coexistir and convivir as identical in every context. — Right: Coexistir means to coexist, while convivir means to live together. — They overlap, but each has uses the other does not: coexistir fits sentences such as Coexisto en paz con los vecinos, while convivir belongs in a different sentence. Check the meaning you want before choosing.
- Wrong: Yo soy coexistido con otras religiones. — Right: Yo he coexistido con otras religiones. — Spanish perfect tenses use haber, not ser: he coexistido, has coexistido, ha coexistido. Ser plus the participle makes a passive, not a perfect tense.
- Wrong: De niño, yo coexistí en la misma casa todos los días. — Right: De niño, yo coexistía en la misma casa todos los días. — For a repeated habit in the past, use the imperfect (coexistía), not the preterite. The preterite (coexistí) is for one finished action.
