Did y Didnt

Te explico:

Es la forma del pasado del verbo auxiliar "DO". En este verbo pasado recae la misma función de auxiliar. En una pregunta donde el verbo necesite el auxiliar y que además sea pasadopues la construyes de manera normal pero teniendo en cuenta que en la frase el pasado recae sobre el DID o DIDN'T por lo que el VERBO NO ESTÁ EN PASADO ya que ya lo estás comunicando al poner el auxiliarDID.

Partícula interrogativa + Auxiliar + Sujeto + Verbo + Complementos

-Where did you go yesterday? (¿Dóndo fuíste ayer?)

-Didn't you gou to the party?(¿No fuíste a la fiesta?)



Seusa did + sujeto + el verbo infinitivo (sin to) con todas las personas

Ejemplo

I went to the supermarket. (fui al supermercado)

Did you go to the supermarket? (¿fuiste al supermercado?)Where did you go? (¿donde fuiste?)

When did you go to the supermarket? (¿cuando fuiste al supermercado?)

*Aquí tampoco usamos DID como verbo, sino comoauxiliar que indica negatividad (didn't / did not) y modo interrogativo en el pasado simple.
*En este caso, no se aplica la regla de tercera persona, ya que DID es el pasado de DO y de DOES también,...
