The Present Perfect Progressive (or Continuous) is a verb tense that is used to express a continuous action that started in the past and is still going on or has just finished. In Greek, it is formed using the perfect tense of the verb ‘to have’ combined with the present participle of the main verb. The action is seen as ongoing or unfinished from the perspective of the present. It can also describe a matter of fact which has taken place at an undefined moment in time.
