The present perfect continuous is used for actions or events that began in the past and continue into the present.
As with the present perfect simple, we use the auxiliary verb “to have” as well as “been” (the past participle of the verb “to be”) and the verb+ing.
|I, you, we, they||have been||talking, studying, waiting…|
|he, she, it||has been||talking, studying, waiting…|

We use the present perfect continuous when we want to express the sense of continuity of an action that began in the past and which continues into the present or which has just finished.
We use it to refer to something that we have been doing over a period of time and therefore we use the “for” and “since”.
If we use the present perfect continuous without a time reference, it means “lately” or “recently”.
Note: As we have learned, we cannot use the continuous tenses with some verbs (see a list of verbs and an explanation here). In these cases, we use the present perfect simple.
