Explanation:

Intransitive verbs: Intransitive verbs are action verbs representing a doable activity which do not require direct object for producing the full meaning of the sentence. In other words the action performed is not directly on the object.

Examples: go, arrive, lie, sleep, sit, sneeze.

Transitive Verbs: Transitive verbs are those in which action is performed directly on some object.

Examples: give, bring, take.

A technique to identify whether a verb is transitive or intransitive is to convert it into passive voice. If it can be converted into passive voice, the verb would be transitive, if not it would be intransitive.

It is also worth noting that some verbs may act as intransitive in one sentence or transitive in another sentence.

For Example:

He ran very fast on the road (intransitive verb). No passive voice of this sentence is possible.

He ran a marathon (transitive verb). Passive voice is possible (A marathon was run by him).
