👉 can, could, may, might, must, shall, should, will, would
Example:
- I can swim.
- She should study more.
- You must wear a seatbelt.

- ✅ I can go now.
- ❌ I can to go now.
- They do not take -s, -ed, or -ing.
- ✅ He can drive.
- ❌ He cans drive.
- They don’t need “do/does” in questions or negatives.
