Concept
Intransitive verb
Résumé
In grammar, an intransitive verb is a verb whose context does not entail a direct object. That lack of transitivity distinguishes intransitive verbs from transitive verbs, which entail one or more objects. Additionally, intransitive verbs are typically considered within a class apart from modal verbs and defective verbs.
In the following sentences, verbs are used without a direct object:
"Rivers flow."
"I sneezed."
"My dog ran."
"Water evaporates when it's hot."
"You've grown since I last saw you!"
"I wonder how old I will be when I die."
The following sentences contain transitive verbs (they entail one or more objects):
"We watched a movie last night."
"She's making promises."
"When I said that, my sister smacked me."
"Santa gave me a present."
"He continuously clicked his pen and it was incredibly annoying to me."
Some verbs, called ambitransitive verbs, may entail objects but do not always require one. Such a verb may be used as intransitive in one sentence, and as transitive in another.

In general, intransitive verbs often involve weather terms, involuntary processes, states, bodily functions, motion, action processes, cognition, sensation, and emotion.
The valency of a verb is related to transitivity. Where the transitivity of a verb only considers the objects, the valency of a verb considers all the arguments that correspond to a verb, including both the subject of the verb and all of the objects.
It is possible to change the contextually indicated sense of a verb from transitive to intransitive, and in so doing to change the valency.
