For and since

We use ‘for’ to measure the amount of time something lasts.

This film will last for two hours.

Come to Ireland for a month!

You can study in Delfin Engluish School for any length of time you wish.

To measure a past time until the present, we use the present perfect, I have + participle.

I have been here for an hour.

I have been speaking for ten seconds

I have lived in Dublin for ten years.

We do not use for with all.

I have been here for ten years

I have been here all my life.

We do not say, I have been here for all my life.

So, when you say for, the next words will be a period of time

For two days

For five minutes

For a while

For three seconds

For one million years

When you say since, the next words will be a point of time

Since three o’clock.

Three o’clock is not a period. It is a moment in time. It is the name of a time

Since Tuesday

Since 1995

Since last Christmas

Since Mary's birthday

I have been living in Dublin since 1996

I have been living in Dublin for eleven years.

I’ve been learning English since I was 12 years old

I’ve been learning English for six years.

Why not visit us here in Delfin English School...

For as long as you like!
