Perfect Progressive Aspect
Any verb (in the past,
present or future) in the
perfect
progressive tense is said to be in the "perfect progressive aspect".
With the exception of verbs in the present perfect progressive tense, such verbs
are used to mark the end of an on-going action. In the present, this aspect
is used for verbs that began in the past and continue into the
present.
