- Wrong: Treating acondicionar and preparar as identical in every context. — Right: Acondicionar means to condition, to fit out, while preparar means to prepare. — They overlap, but each has uses the other does not: acondicionar fits sentences such as Acondiciono la sala para el concierto, while preparar belongs in a different sentence. Check the meaning you want before choosing.
- Wrong: Yo soy acondicionado la casa con aire acondicionado. — Right: Yo he acondicionado la casa con aire acondicionado. — Spanish perfect tenses use haber, not ser: he acondicionado, has acondicionado, ha acondicionado. Ser plus the participle makes a passive, not a perfect tense.
- Wrong: De niño, yo acondicioné el gimnasio con material nuevo todos los días. — Right: De niño, yo acondicionaba el gimnasio con material nuevo todos los días. — For a repeated habit in the past, use the imperfect (acondicionaba), not the preterite.
