Common mistakes
- Wrong: Yo bucea en el mar con las gafas. — Right: Yo buceo en el mar con las gafas. — The person matters: bucea is the él/ella/Ud. form, while the yo form is buceo. Using the third-person form with yo is one of the most common beginner errors.
- Wrong: Ayer yo buceo entre los corales de la costa. — Right: Ayer yo buceé entre los corales de la costa. — The present and the preterite are different tenses: buceo is happening now, while buceé is a finished action in the past. Use the preterite with ayer.
- Wrong: Treating bucear and nadar as identical in every context. — Right: Bucear means to dive, to snorkel, while nadar means to swim. — They overlap, but each has uses the other does not: bucear fits sentences such as Buceo en el mar con las gafas, while nadar belongs in a different sentence. Check the meaning you want before choosing.
- Wrong: Yo soy buceado entre los corales de la costa. — Right: Yo he buceado entre los corales de la costa. — Spanish perfect tenses use haber, not ser: he buceado, has buceado, ha buceado. Ser plus the participle makes a passive, not a perfect tense.
- Wrong: De niño, yo buceé en la piscina del hotel todos los días. — Right: De niño, yo buceaba en la piscina del hotel todos los días. — For a repeated habit in the past, use the imperfect (buceaba), not the preterite. The preterite (buceé) is for one finished action.
