MODAL AUXILIARY VERBS AND HELPING VERBS (DETAILED EXPLANATION WITH EXAMPLES)
INTRODUCTION
In English grammar, verbs are very important because they show action, state, or condition. Along with main verbs, English also uses special verbs called helping verbs. Modal auxiliary verbs are a special type of helping verbs. They help the main verb to express ideas like ability, permission, possibility, necessity, obligation, advice, and intention.
PART 1: HELPING VERBS (AUXILIARY VERBS)
DEFINITION OF HELPING VERBS
Helping verbs are verbs that help the main verb to form tense, voice, mood, or emphasis. They do not show action alone. They always come before the main verb.

Do
These verbs change their form according to tense and subject.

PART 2: MODAL AUXILIARY VERBS
