Negaciones don't / doesn't (presente simple)

"To negate in the present simple use don't (I/you/we/they) or doesn't (he/she/it) + base verb."

La regla

Para negar en presente simple usa don't (I/you/we/they) o doesn't (he/she/it) + verbo en infinitivo.

El inglés no pone solo no antes del verbo como el español. Necesita el auxiliar do/does + not. Forma corta: don't / doesn't. Tras el auxiliar el verbo principal va en infinitivo, sin -s aunque el sujeto sea he/she/it.
