The Perfect Tense tells us when a continuing action or existence will end, ends, or ended in relation to a specific time, or reference point. In other words, perfect tense shows when action happening over time ends. The auxiliary to have is combined with the past participle (V-p.part) of the verb.

• Past Perfect – Action/existence that continued to occur until a moment in the past.
• Present Perfect – Action/existence started in the past and continues to occur to the present moment or the action ended at some earlier time.
• Future Perfect – Action/existence will continue to occur until a time in the future.
