v Infinitive or Gerund


¿A QUÉ HACEMOS REFERENCIA?
Nos referimos a cuándo utilizar un infinitivo y cuándo utilizar un gerundio después de otro verbo, es decir, las reglas que determinan cuándo utilizar uno u otro.

to walk walking

* Recuerda que hay casos en los que se pueden utilizar ambas formas. A veces esas dos estructuras son completamente intercambiables, pero en otros casos el significado cambia dependiendo de la estructura elegida.


¿CUÁNDO USAMOS EL INFINITIVO?
El infinitivo se utiliza cuando va seguido de ciertos verbos como want, forget, need, prepare, expect, etc.
Yo quiero ir al campo.
I want to go to the country.

Por otro lado, se utiliza cuando está situado detrás de adjetivos o adverbios.

Eso es difícil de recordar
That is difficult to remember.

* Recuerda que esto mismo sucede si estos adjetivos o adverbios van acompañados de las partículas 'too' y 'enough'.

Eso es demasiado difícil de recordar
That is too difficult to remember.

Vamos a utilizar el infinitivo en el caso de que el verbo principal esté acompañando de un pronombre objeto.
Me dijo que abriera la puerta.
He told me to open the door.

¿CUÁNDO USAMOS EL GERUNDIO?
El gerundio también lo utilizamos principalmente cuando va seguido de otro grupo de verbos como admit, avoid, consider, suggest, mind, imagine, etc.



Mi hermano sugirió ir al campo.
My brother suggested going to the country.

Por otro lado, el gerundio siempre se utiliza cuando va seguido de una preposición, es decir, todo verbo seguido de preposición debe ir en-ing.

Ellos fueron después de ir al cine.
They went after going to the cinema.

Además, cuando la frase comienza con un verbo que hace de sujetotambién utilizamos un gerundio.
Escuchar música es mi hobby preferido.
Listening to music is my favourite hobby.

Por ultimo, el gerundio se utiliza mucho en prohibiciones o carteles con mensajes cortos.
Prohibido aparcar.
No parking.


¿CUÁNDO SE UTILIZAN INDISTINTAMENTE?
Existe un grupo de verbos que nos permiten utilizar ambas estructuras indistintamente, es decir, sin cambiar el significado. Entre estos verbos encontramos begin, intend, start, pefer, etc.
Ella empezó a estudiar francés.
She began learning French. / She began to learn French.

*1También se utiliza con verbos como 'like', 'hate' o 'love'. Sin embargo es mucho más común ver la estructura con gerundio.
*2La diferencia en muchos casos está que cuando hablamos en general utilizamos el gerundio (I.e. I like playing tennis) y cuando hablamos de situaciones específicas utilizamos el infinitivo (I.e. I hate to swim here).


¿CUÁNDO CAMBIA EL SIGNIFICADO?
Con otro grupo de verbos también podemos utilizar ambas estructuras, pero el significado cambia. Entre este tipo de verbos encontramos remember, try, stop y forget.

Él intentóabrir la ventana.
He triedto open the window.
Él probóa abrir la ventana.
He triedopening the window.


¿QUÉ DEBO RECORDAR?
Los puntos importantes que debemos recordar son los siguientes:
  • Recuerda que en la sección de 'Verb Patterns' hemos visto otros aspectos a tener en cuenta con respecto a este tema.
  • Distinguir entre una forma y otra en muchos casos puede resultar difícil, pero el uso va a ser el mejor aliado para aprender cómo utilizar esta estructura de manera correcta.
