Overview of Modal Verbs: How and When to Use Them
Modal verbs are helping verbs that show necessity, possibility, ability, permission, or advice. They do not change form and are followed by the base form of a verb.
1. Must
Use for: Strong necessity or logical conclusion.
Examples:- You must wear a seatbelt. (necessity)
- He must be tired after working all day. (logical conclusion)
Tip: Use must for strong advice or certainty.
For past obligations, use had to.
2. Can't
Use for: Strong negative certainty or impossibility.
Examples:- He can't be serious! (certainty)
- That can't be the right answer. (impossibility)
Tip: Use "can't" when something is logically impossible.
3. Should
Use for: Advice or mild obligation.
Examples:- You should drink more water. (advice)
- She should apologize. (mild obligation)
Tip: "Should" is softer than "must."
Negative form is "shouldn't" for advice against something.
4. Might
Use for: Possibility (less certain than "may").
Examples:- I might go to the party. (possibility)
- It might rain later. (uncertain possibility)
Tip: Use "might" when you're unsure about something.
5. Can
Use for: Ability or permission.
Examples:- I can swim. (ability)
- Can I use your phone? (permission)
Tip: Use "could" for a polite request, permission, or past ability.
6. Have to
Use for: Obligation or necessity.
Examples:- I have to finish my homework. (necessity)
Tip: "Have to" is similar to "must" but more common in everyday speech.
In negative, use "don't have to" to express a lack of obligation.
7. Bound to
Use for: Strong certainty or inevitability.
Examples:- He is bound to forget if you don't remind him. (certainty)
Tip: Use when something is very likely to happen.
8. 'd Better (Had Better)
