This document discusses the difference between transitive and intransitive verbs. Transitive verbs are verbs that take a direct object, such as "broke the window." Intransitive verbs do not take a direct object and describe actions where nothing receives the action, such as "cried." It is important to understand the difference, as many students and even native speakers can confuse whether a verb is transitive or intransitive. The document provides examples of common transitive and intransitive verbs and warns that prepositional phrases and adverbs do not make an intransitive verb transitive.
