What are transitive verbs?

A transitive verb is a verb that requires a direct object (e.g., a noun, pronoun, or noun phrase) that indicates the person or thing affected by the verb.

The direct object usually comes immediately after the verb (e.g., “Karen is taking a photo”). Without a direct object (in this case, “a photo”), sentences containing transitive verbs do not make sense (e.g., “Karen is taking”).
