Using Since And For
The prepositions since and for are commonly used with the present perfect and perfect continuous tenses.
Use since to say when something begins. Example: since Monday, since last year, since morning etc.
Use for to say how long something lasts. Example: for two hours, for two years, for two weeks, for a long time etc.
Read the example given below.
- The baby started sleeping at 4 o'clock. She is still sleeping. It is now 6 o'clock.
Here we are talking about a situation that started in the past and has continued up to the present. We can combine these three sentences into one in two different ways.
- The baby has been sleeping since 4 o'clock. OR The baby has been sleeping for two hours.

1. Rahul arrived in Mumbai in 2003. He has lived in Mumbai for ten years. He is still living there.
