Past Simple Tense

The past simple is used to talk about completed actions in the past. It tells us when something happened — yesterday, last week, two years ago — and that action is finished.

When to use it

- Completed actions: I watched a movie last night. - Past habits: She walked to school every day. - Historical facts: Einstein developed the theory of relativity.

Regular vs irregular verbs

Most verbs add -ed at the end: walk → walked, play → played. But many common verbs are irregular and must be memorized: go → went, eat → ate, see → saw.
