The present perfect progressive tense is used to describe an activity that began in the past and continues into the present. It is formed using "have/has been" plus the present participle of the verb. Examples of its use include "They have been playing for two hours" and "It has been raining all day." Time expressions like "for," "since," "all morning," etc. are often used with this tense. Certain stative verbs that describe a state of being cannot be used in the progressive tense. When used without a specific time mention, it expresses a general ongoing activity recently.
