Here's how:
Intransitive: When "running" describes an action without a direct object, it's intransitive.
* Examples:
* "The dog is running in the park."
* "I'm running late."
* "She enjoys running in the mornings."
Transitive: When "running" describes an action with a direct object, it's transitive.
* Examples:
* "He is running the business."
* "The team is running a new marketing campaign."
* "She ran the marathon."
In these examples, "business," "marketing campaign," and "marathon" are the direct objects of the verb "running."
