Los verbos auxiliares son los verbos de apoyo que trabajan junto a los verbos principales para construir tiempos, preguntas y negativos. En inglés, los tres auxiliares principales son do, be y have. Entender exactamente qué hace cada uno hará que toda tu gramática sea más clara. 🎯

1. DO: preguntas y negativos en presente y pasado simple 📋

Do / does / did se usan para construir preguntas y negativos cuando no hay otro auxiliar:
