Use of Modal Verbs – can, could, may, might

Modal verbs are special verbs that give more information about the function of the main verb that follows them. They are used to express possibility, ability, permission, advice, necessity, or future intentions.

Form

• Modal verbs are always followed by the base form of the main verb (without “to”).
• They do not change form depending on the subject (no -s in the third person).
• Negatives and questions are formed without auxiliary verbs (e.g., Should I go?, You must not lie.)
