Actually, do / does / did aren’t just “action” verbs.
They’re little helpers in English — used to ask questions or make negatives.
Let’s break it down with 3 super simple rules:
1. Do — Present / Many People
Use for: I / you / we / they and plural nouns
Example:
Do you like apples?
2. Does — Present / One Person
Use for: he / she / it and singular nouns
Example:
Does she sing?
3. Did — Past / Everyone
Use for: all subjects, when you’re talking about the past
Example:
Did you play?
