Core Fundamentals of Modal Verbs in English Grammar

Introduction

Modals are an important part of English grammar. They help us express ideas like ability, permission, possibility, advice, and obligation.

Without modals, our sentences would sound incomplete or unclear. They make communication more polite, clear, and meaningful.

In simple words, modals are helping verbs that show mood, possibility, or necessity in a sentence.

What Are Modals?

Modals (Modal Verbs) are special helping verbs used with the main verb to express different meanings.

They are always used with the base form of the verb.

Structure:

Subject + Modal + Base Verb

Example:
