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?
