Present Perfect Continuous This tense is used to express the action which started in the past and is still going on in the present.The present perfect continuous tense is used to describe or suggest an event that is now taking place. This tense is used to represent an occurrence that started in the past and will continue. When there is no indication of time, it is sometimes used to describe an activity or event that began in the past and is now only done or over.
This tense denotes a present-tense action that is continuing. In other words, it represents an ongoing action that has not yet been accomplished at the time of speaking. As previously said, when an activity takes place at the time of speaking. This tense is used when a future activity is specified without indicating when it will occur.
Also, when discussing a planned or arranged event or action that is scheduled to occur at a specific time in the future, and in circumstances when the action or event is taking place but not necessarily while we are speaking.
In a changing situation, the present continuous tense is utilized. We employ adverbs like 'always,' which characterize an often occurring action.
