The Present Perfect Continuous is used to describe an activity which started in the past and is continuing at the moment.
When do we use the Present Perfect Continuous?
An unfinished action
When you are describing an activity, which has been happening up until this point, i.e. something which started in the past and is continuing at the moment.
Examples of an unfinished action
- Sarah has been teaching English for 12 years.
- They have been talking non-stop for three hours!
- Why haven’t you been reading your new book?
It is often used with how long, for, and since.
Examples with how long, for, and since:
- How long have you been studying English?
- We have been living here since last year.
- I have been waiting for the bus for half an hour.
We can’t use the present perfect continuous with stative verbs
Stative verbs are verbs like believe, agree, depend, contain (for a longer list of stative verbs and grammar explanations, click here). Stative Verbs are sometimes also called Non-Continuous Verbs as they refer to things you can’t actually see the somebody doing in the physical sense, e.g. love, hate, cost, care and so on.

Examples of a habit or temporary situation:

When something was happening until a short time ago and ends in a defined result.
