When do I use past simple instead of present perfect?

Use past simple when the time period is finished and specific: 'I saw her yesterday', 'We moved in 2020'. Use present perfect when the time is unfinished or unspecified: 'I have seen her this week', 'We have moved house'. Finished past = past simple; relevant to now = present perfect.

Why is 'I didn't went' wrong?

'Did' already signals the past, so the main verb stays in its base form: 'I didn't go'. The same rule applies to questions: 'Did you go?' — never 'Did you went?'. Only one element of the verb phrase shows past tense.

How do I form the past simple of regular verbs?

Add -ed to the base form: walk → walked, talk → talked. For verbs ending in -e, just add -d: live → lived. For verbs ending in consonant + y, change y to i: study → studied. For short verbs ending in consonant + vowel + consonant, double the final consonant: stop → stopped.

Are there shortcuts for learning irregular verbs?

Group them by pattern. Same form throughout: cut/cut/cut, put/put/put. Same past and participle: buy/bought/bought, find/found/found. All three different: go/went/gone, see/saw/seen, write/wrote/written. Practising the most common ~50 covers most of everyday English.

Which time markers usually signal past simple?

'Yesterday', 'last week/month/year', '… ago' (two days ago), 'in 2020', 'when I was a child', 'on Monday' (a past Monday). These all point to a finished, specific time — the strongest signal that you should use past simple, not present perfect.

Can I use past simple for past habits?

Yes: 'We played outside every day after school' is correct. You can also use 'used to + base verb' for past habits or states that no longer happen: 'We used to play outside every day'. Both are acceptable, but 'used to' more clearly contrasts past with present.

The past simple tense describes completed actions, states, or habits in the past, usually with a specific finished time. Regular verbs add -ed; irregular verbs change form (go → went, see → saw).

When to Use Past Simple

•Finished actions in the past: I visited Paris in 2022.
•A series of completed actions: She packed her bag, locked the door, and left.
•Past habits or routines: We often played outside after school.
•Past states: They lived in Rome for three years (past, finished).
•Questions/negatives with did: Did you watch the game?
