The present perfect continuous tense is a vital aspect of English grammar that allows speakers and writers to describe actions that began in the past and are still ongoing or have recently stopped, with a focus on the duration of those actions. This tense is particularly useful for expressing the continuity of an action and its relevance to the present.
