Here's how to tell:
* Transitive: The verb has a direct object, the thing that receives the action.
* Example: "He started the car." (The car is the direct object)
* Intransitive: The verb doesn't have a direct object.
* Example: "The party started at 8pm." (There is no direct object receiving the action of starting)
