Verb is a word which denotes action or being or possession. All sentences must have verb with a subject.

For example:

1. Yuvraj caught the ball

caught what ? - the ball, so ball is object of the verb caught.

If we frame a question using the verb and the word 'what' or 'whom', the word that answers the question is the object of the verb.

Types of Verb

A. Transitive Verbs

Some verbs do not convey a complete meaning by themselves. For example

1. The chief minister made

2. Deepika ate

If we add objects to these verbs , the meaning becomes complete:

1. The chief minister made an appeal

2. Deepika ate apples.

A verb that requires an object to complete its meaning is called a transitive verb.

B. Intransitive Verbs

Some verbs are complete by themselves. They do not reuire an object to complete the senses. For example:

1. The stars are twinkling.

2. The child smiled.

A verb that does not require an object to make sense but makes good sense by itself is called an intransitive verb.

C. Incomplete Verbs, complements

Verbs like be (is,am,are,was,were,will be,shall be, etc.) appear , seem and look are incomplete verbs. For example:

1. The bus is

2. The mother was

But  these verbs do not require objects to complete the sense. Verbs denoting action or possession can have objects. But these verbs neither action nor possession. These verbs are call verbs of incomplete predication. Let us complete them.

1. The bus is late.

2. The mother was cooking food.

The words late, cooking food that we have used to complete the sense are called complements. A complement along with the verb forms a complete predicate.
