* Transitive: It can take a direct object.
* Example: "She laughed a hearty laugh." (The direct object is "a hearty laugh").
* Intransitive: It can also be used without a direct object.
* Example: "He laughed at the joke." (The prepositional phrase "at the joke" modifies the verb but isn't the direct object).
Therefore, it depends on the sentence structure whether "laugh" is acting as a transitive or intransitive verb.
