What is the difference between present perfect and past simple?

Past simple describes a finished action at a specific past time ("I visited Paris in 2019"). Present perfect describes a past action with present relevance or no specific time ("I have visited Paris three times").

When do we use "since" vs "for" with present perfect?

Use "since" with a starting point in time ("since 2020", "since Monday"). Use "for" with a duration ("for five years", "for two hours").

Can I use the present perfect with "yesterday" or "last week"?

No. Present perfect cannot be used with finished time expressions. Use past simple instead: "I saw him yesterday" (not "I have seen him yesterday").

What Is the Present Perfect Tense?

The present perfect tense is used to describe actions that happened at an unspecified time in the past or actions that continue up to the present. It is formed using have/has + past participle. Example: She has finished her homework.

The present perfect is often compared with the past simple tense, which describes actions completed at a specific time in the past.
