Resumen

Have to + Infinitive: Expressing Obligation

Puntos clave

Have significa tener, pero si se le añade to y un verbo en infinitivo, se convierte en la expresión "tener que hacer algo".

Info 1: "Have to" in affirmative

Have to es una expresión que se utiliza para indicar que algo es necesario u obligatorio. Suelen ser acciones que se nos obligan externamente, es decir, no es algo que queramos hacer, sino algo que debemos hacer.

La fórmula para emplear have to en una frase afirmativa es la siguiente:

Sujeto + have/has + to + verbo en infinitivo

Ejemplos

I have to go back home at 9 o'clock

She has to go to the bank

Recuerda que: También puede usarse have got to oralmente de manera informal o de forma escrita en textos formales.

Info 2: "Have to" in negative

La expresión have to en negativo indica que algo puede hacerse o no, ya que no es obligatorio. La estructura para crear frases en negativo es así:

Sujeto + don't/doesn't + have + to + verbo en infinitivo

Ejemplos

I don't have to study today

He doesn't have to wear a white shirt

Info 3: "Have to" in interrogative

Para hacer preguntas sobre si es necesario realizar alguna actividad, se usa el have to en forma interrogativa. Su estructura es la siguiente:

Do/Does + sujeto + have + to + verbo en infinitivo

Ejemplos

Does she have to read the book?

Do we have to work on Sundays?

Recuerda que: Aunque funcione como tal, have to no es un modal verb sino un semi modal, por lo que las preguntas deben empezar por el auxiliar do o does.
