Present Perfect Simple and Present Perfect Continuous
We use the present perfect tense to talk about things where there is a connection between the past and the present.
- He’s written 16 books.
He started writing books at some time in the past. So far, he has written 16 books. He may write more books.
As well as the present perfect simple, we can use the present perfect continuous tense to talk about events with a connection to the present.

We can use the present perfect simple to talk about how long when we view something as permanent. But the present perfect continuous is often used to show that something is temporary.
Often there is very little difference between the present perfect simple and the present perfect continuous. In many cases, both are equally acceptable.
