In this post I am going to explain the difference between for and since.
For and since are two particles that most of the times we'll find them in a perfect tense, such as the Present Perfect, Present Perfect Continuous, Past Perfect or Past Perfect Continuous. Both are use to express a period of time.
When do we have to use FOR?
For is used to express a period of time, for instance two weeks, one year, a couple of months...
Have a look at the following example:
- I have learnt English for twelve years.
With this sentence what we want to express is that I started learning English in 2007 and I continue studying English now.
When do we have to use SINCE?
Since is used to express the exact moment when an action started.
- I have learnt English since 2007
Do you see the difference??
