A verb is transitive when it needs an object to complete its meaning; that is, when the action passes over (Latin, transire, to pass over) from the subject or doer to the object or receiver; as,

He hit the ball.

A verb is intransitive when it needs no object to complete its meaning; as,

The crowd cheered.

Some intransitive verbs require a predicate noun or pronoun in the nominative case, or an adjective, to complete their meaning. They are the verbs be, become, appear, seem, feel, taste, look, smell; as,

Adjective: The berries taste sour.
Noun: John is my brother.
Pronoun: It is I.

Such verbs are sometimes called copulatives.
