Transitive verbs are verbs that have a direct object. They indicate situations in which something is acting on something else. For example, ‘hit’ is a transitive verb in ‘I hit the ball.’  Here the ball is being acted on; it is the direct object. The subject of a transitive verb is the person performing the action.

Intransitive verbs are verbs that have no direct object. They indicate events in themselves. For example, in the sentence ‘I go’ the word is intransitive because you can’t ‘go’ something. The subject in ‘I go’ is ‘I.’
