Complete Differences Explained in Depth With Clear Examples
Completed Action or Event at a Definite Time: Past Simple Only
We use Past Simple when the time is clear, fixed, and definite. A definite time which you can easily explain.
Examples:

- He supported me a year ago.
- Mona wrote this article months ago.
- We did not see him from January 2000.
- He stopped calling me when he went to London.
- Jon lived in the village when he had no money.
👉 All bold parts show a clear, definable time → So only Past Simple works.
Completed Action or Event at an Indefinite Time: Past Simple or Present Perfect
When the time is not clear, definite, or fixed. An indefinite time which you cannot easily explain, we use Past Simple or Present Perfect.
Common Time Words: already, recently, finally, earlier, occasionally, lately, before, ever.
Examples:
- I recently saw you there. or I have recently seen you there.

- We did not see him earlier. or We have not seen him earlier.
- He occasionally stopped calling me. or He has occasionally stopped calling me.

👉 All bold parts show a unclear, indefinable time → So Past Simple or Present Perfect Tense works.
Completed Action or Event in Unspecified Time: Past Simple or Present Perfect
When an action or event has been completed and we do not show or mention any time in a sentence, we use Past Simple or Present Perfect.
Examples:
- I saw you there. / I have seen you there.
