Verb to be — Negative

Negación de be: am not / isn't / aren't

Para negar el verbo be en inglés solo añades NOT después de él. No necesitas auxiliar DO/DOES — be se niega directamente: am not, is not, are not. Es diferente al presente simple con otros verbos, donde sí necesitas DO/DOES.

Las contracciones negativas son is not → isn't y are not → aren't. Sin embargo, am not NO tiene una contracción estándar en inglés: 'amn't' NO EXISTE. La única forma negativa de 'I am' es 'I am not' o, en forma contraída, 'I'm not'. Nunca uses 'amn't'.

Hay dos posibles contracciones cuando el sujeto no es I: puedes contraer el pronombre con be (he's not, she's not, they're not) O puedes contraer be con not (he isn't, she isn't, they aren't). Ambas son igualmente válidas y comunes.

Los hispanohablantes tienden a agregar DO/DOES antes de be para negar, lo cual es incorrecto: 'She doesn't is happy' es un error grave. La forma correcta es simplemente 'She isn't happy' o 'She is not happy'.

El verbo be negativo se usa para negar identidades, características, edades, profesiones, nacionalidades y ubicaciones. Recuerda: nunca se dice 'I don't am' — siempre 'I am not' o 'I'm not'.
