¿Qué son las negaciones y preguntas con did?

Did not dice no en pasado y Did pregunta por el pasado: I did not go. Did you see? Did vale para todas las personas: I, you, he, she, it, we y they usan la misma palabra. El verbo principal nunca cambia después de did.

La regla

Para negar se usa did not con el verbo base: She did not eat. Para preguntar, Did pasa delante del sujeto: Did she eat? Las respuestas cortas conservan did: Yes, I did. No, I did not.

Un solo did basta. Como did ya marca el pasado, detrás nunca va -ed ni un pasado irregular.

Forma

Ejemplos

• I did not watch TV yesterday.

Errores frecuentes

• ❌ I didn't went. → ✅ I didn't go. Did ya marca el pasado; el verbo queda en base.
• ❌ Did he went? → ✅ Did he go? Una sola marca de pasado: nunca did más went.
• ❌ Do you went yesterday? → ✅ Did you go yesterday? Do es presente; yesterday pide did.
• ❌ They went not. → ✅ They did not go. La negación necesita did.
