What is a modal verb and how do I use it?
Concise Direct Answer
A modal verb is a helping verb that expresses ability, permission, advice, or necessity. Modals are followed directly by the base form of the main verb without using "to." Understanding these structural guidelines helps you select the correct register and communicate your intentions clearly during daily English interactions.
Detailed Explanation & Context
A modal verb is an auxiliary verb (e.g. can, should, must) that expresses necessity, possibility, or permission. They modify the main verb that follows and do not change form with subject pronoun shifts.
