Modal verbs are a category of auxiliary verbs used in English to indicate the attitude or modality of the speaker towards the action or state described by the main verb in a sentence. Modal verbs modify the meaning of the main verb, expressing various nuances such as possibility, necessity, ability, permission, suggestion, and obligation. These verbs are also used to create different tenses and moods in English.
The most common modal verbs in English are:
- Can: Used to express ability, possibility, or permission.
- Example: I can play the guitar. (ability) / Can I go to the party? (permission) / It can rain later. (possibility)
- Could: Often used as the past tense of “can,” expressing past ability, possibility, or permission. It can also be used to make polite requests.
- Example: When I was younger, I could run faster. (past ability) / Could I borrow your pen, please? (polite request)
