Present Perfect Verb
現在完了 (げんざいかんりょう)
FUN FACT: "There are about 189 irregular verbs in the English language."
DEFINITION: The present perfect verb (PPV) is composed of two elements:
The appropriate form of the helping verb 'to have'.
The Past Participle of the main verb. The past participle of a regular verb is "verb+ed": played, looked, watched, etc.
NOTE: Be careful of irregular verbs because when they switch to the past participle the entire verb changes: drink-->drunk / sleep-->slept / rise-->risen.
The PPV is used to indicate a link between the present and the past. It is used to describe:
An action or situation that started in the past and continues in the present: I have played the piano since I was a child. (...and I still do.)
An action performed during a period that has not yet finished: I have worked hard this week. (...and the week isn't over yet.)
A repeated action in an unspecified period between the past and now: I have lived in Japan for five years.
An action that was completed in the very recent past, expressed by "just": I have just finished my work.
An action when the time is not important: She has studied Japanese, English and Chinese. (...the result of his reading is important)
