Present Simple — Negative

Cómo negar hechos y rutinas

El Present Simple Negativo es como añadir un operador lógico NOT a una expresión booleana. En lugar de declarar un hecho, lo niegas usando un "interruptor" llamado auxiliar DO/DOES.

En programación, muchos lenguajes usan ! o not para invertir un valor. En inglés, necesitas un auxiliar especial para hacer esto: DO para I/you/we/they y DOES para he/she/it. Sin este auxiliar, la negación no compila — es un error de sintaxis.

La fórmula es: SUJETO + DON'T/DOESN'T + VERBO_BASE. Cuando usas DOESN'T, el verbo vuelve a su forma base (trabaja como un reset). No puedes decir 'doesn't works' — el auxiliar ya absorbió la marca de tercera persona.

El Present Simple Negativo se usa para negar hechos, rutinas y hábitos: 'I don't drink coffee.' 'She doesn't work on Saturdays.'

Una negación doble (doble negativo) NO es válido en inglés estándar: 'I don't know nothing' es incorrecto. La forma correcta es 'I don't know anything' o 'I know nothing'.

El verbo BE tiene su propia forma de negación: I am not, you aren't, he/she/it isn't, we aren't, they aren't. NO uses DO/DOES con BE.

Las contracciones son muy comunes: don't (do not), doesn't (does not). En conversación formal, usa la forma completa.

Para enfatizar la negación, puedes usar DO/DOES + NOT + verbo: 'I do NOT like this.' Es más enfático que 'I don't like this.'

Los adverbios de frecuencia van ENTRE el sujeto y el auxiliar negativo: 'I don't always like coffee.' 'She doesn't usually work late.'

Las respuestas cortas negativas usan el mismo auxiliar: 'Do you work?' — 'No, I don't.' 'Does she play?' — 'No, she doesn't.'
