The
Present Perfect Continuous (also known as the
present perfect progressive) is a verb tense used to describe something that started in the past and continues in the present.
Example:
I have been reading the book War and Peace for a month.
Anna has been competing in flute competitions recently (and she will continue to do so).
The formula for the present perfect continuous tense is: has/have been + [present participle (root form of verb + -ing)].
