Can and Could: Definition and Synonyms
Can and Could – Definition and Part of Speech
The words can and could are modal auxiliary verbs used in English to express ability, possibility, permission, or hypothetical situations.
- Can: Typically refers to the present tense and is used for expressing general ability (e.g., “I can swim”) or seeking/granting permission (e.g., “Can I leave early?”).
- Could: Serves as the past tense of can or a form used to express a conditional possibility or politeness in requests (e.g., “If it were possible, we could travel together”).
Both words are primarily used for auxiliary functions rather than serving as main verbs themselves.
