What is the difference between/Cual es la diferencia entre "for / Since"?

Question

Cuando debo de escribir for ó since a la hora de hablar de un periodo de tiempo haciendo el Present Perfect Continuous

Answer 1

Hola,

Se usa 'for' con un intervalo del tiempo. Year, day, hour.

Se use 'since' con un punto del tiempo desde que algo empezó.

Se usa ambos con el presente perfecto (have/has + PP) o con el presente perfecto progresivo (have/has + been + -ing)

Por ejemplo:

I've been living in this house for 5 years.

I've been living in this house since 2006.

I have worked here for a year.

I have worked here since 2010.

I've been studying Spanish for 5 months.

I've been studying Spanish since June.

Perdona mi español

I have been studying Spanish since graduating high school. (from a certain point in past time up to the present)
