Verbs express actions or states of being. There are two main types of verbs: helping verbs and main verbs. Helping verbs like "be", "have", and "do" are used along with main verbs. Verbs can also be classified as transitive or intransitive, regular or irregular, dynamic or stative based on whether they take a direct object, their conjugation patterns, and whether they describe an action or state of being.

2. What is a Verb?
A verb express action, events, or states of being. Many verbs
give the idea of action, of "doing" something.
0 Run, fight and work.
But some verbs do not give the idea of action; they give the
idea of existence, of state, of "being".
0 Be, exist, seem and belong.

3. A verb always has a subject.
