What Does ‘Can’ Mean in English?
Can is a modal verb. We use it to talk about ability. It means ‘poder’ in Spanish.
You use can to say that someone has the skill or the possibility to do something.
How to Use ‘Can’ for Positive Ability (+)
To say what someone can do, follow this simple structure:
- Subject + can + base form of the verb
The base form of the verb is the infinitive without ‘to’. For example, swim, not to swim.
How to Use ‘Can’t’ for Negative Ability (-)
To say what someone cannot do, or does not have the ability to do, use can’t.
Can’t is the short form of cannot. It is very common in spoken and written English.
- Subject + can’t + base form of the verb
Remember: ‘Can’ is Special!
Can is a modal verb, so it has special rules:
- It does not change for he, she, 或 it. You do not add -s.
- You always use the base form of the next verb. Do not use to before the verb.
- You do not use do 或 does with can for negatives. Just use can’t.
