❌ Errores frecuentes — Common Mistakes
❌ Error 1: Hemos comidos juntos.
✅ Correcto: Hemos comido juntos.
Por qué importa: The past participle in the compound perfect tense is invariable — it never changes for gender or number. Comido stays comido whether the subject is yo, nosotros, or ellas. Adding -s to make it plural is wrong. The only context where a past participle does agree is when it is used as an adjective (e.g. La puerta está abierta — there, abierta agrees with the feminine puerta). In the perfect tense, never touch the participle.
❌ Error 2: Se hablan inglés en esta tienda.
✅ Correcto: Se habla inglés en esta tienda.
Por qué importa: In the se-passive, the verb must agree with the grammatical subject — the noun that follows it. Inglés is singular, so the verb is singular: se habla. The plural form se hablan would only be correct if the following noun were plural — for example, Se hablan muchos idiomas aquí. (Many languages are spoken here.) The se-passive IS sensitive to number, unlike the impersonal se + infinitive construction. Check what noun follows se and match the verb to it.
