* v tr: This stands for "verb transitive." A transitive verb requires a direct object to complete its meaning. The action of the verb is transferred to something or someone.
* Example: "She wrote (v tr) a letter." (The object of the verb "wrote" is "a letter.")
* v intr: This stands for "verb intransitive." An intransitive verb does not require a direct object. The action of the verb is complete within itself.
* Example: "The birds flew (v intr) away." (There's no object receiving the action of "flew.")
In short:
* Transitive verbs have a direct object (something or someone receiving the action).
* Intransitive verbs do not have a direct object.
Some verbs can be both transitive and intransitive, depending on how they are used.
* Example: "He closed (v tr) the door." (transitive)
"The door closed (v intr)." (intransitive)
