Transitivity is a concept in linguistics that describes how relationships between subjects and objects in a sentence are structured. In a transitive verb construction, the action of the verb is directed toward an object. For example, in the sentence "The cat (subject) chased (verb) the mouse (object)," the verb "chased" requires an object to complete its meaning. In contrast, intransitive verbs do not take a direct object. For instance, in "The cat (subject) sleeps (verb)," there is no object receiving the action. Understanding transitivity helps clarify how sentences are formed and how meaning is conveyed in language.
