present perfect
Noun: A grammatical tense that expresses an action or state that was completed at some indefinite time in the past but has relevance to or a connection with the present moment. It is formed by combining the present tense of the auxiliary verb "have" with the past participle of the main verb.
The present perfect is used to describe: 1. Experiences in an unspecified past: To talk about life experiences without mentioning a specific time. * I have visited Paris. 2. Recent past actions with present results: To describe a past action where the result or effect is important now. * She has lost her keys, so she can't get in. 3. Actions that started in the past and continue to the present: Often used with "for" (duration) or "since" (starting point). * He has worked here for ten years. * We have lived here since 2015. 4. Actions completed in a period of time that is not yet finished: Such as "today," "this week," or "this year." * I have written three emails this morning. (It is still morning.)
- Contrast with Simple Past: The present perfect connects the past to the present. The simple past describes an action completed at a specific, finished time in the past.

- Simple Past: I finished my homework at 5 PM. (The time is specified and complete.)

- Have you ever been to Japan?
- I have never tried bungee jumping.
