Breaking Down the Present Perfect Tense
The Present Perfect Tense tells something about an action that has completed in immediate past, or at the time the statement is made. Present perfect tense may also refer to habitual or repeated past action.
This verb tense is formed by adding either one of the auxiliariesOpens in new window has or have (as appropriate) to the past participle of the main verb.
The present perfect tense stresses emphasis on:
1. Actions that happened in the past at an unspecified time — The present perfect tense shows an action has happened (or never happened) before now, the exact time is not important. If there is a specific mention of time, the simple past is used i.e. “I saw his mum yesterday”. But here in present perfect tense we simply say “I saw his mum”.
2. Actions that began in the past and still going on in the present — This tells something about a repeated action that has begun before now.
3. Actions with a length of time — The present perfect tense, when used with for or since, expresses a situation that began in the past and continues to the present. In the examples below, observe the difference between since and for: since + a particular time, and for + duration of time.
The present perfect has this meaning primarily for those verbs that are usually not used in any of the progressive tenses. This meaning is exactly the same as the meaning of the present perfect progressive tense.
