Present Perfect Continuous Tense With Examples:

The present perfect continuous tense, also known as the present perfect progressive tense, is used to describe an action that started in the past, has continued up to the present, and may continue into the future. This tense is formed using the present perfect of the verb "to have" (have/has), the past participle of the main verb, and the present participle of the main verb (-ing form).

The formula for the present perfect continuous tense is:

[ text{Subject} + text{has/have} + text{been} + text{verb-ing}]
