In English grammar, a direct object is a noun, noun phrase, or pronoun that identifies what or who receives the action of a transitive verb in a clause or sentence. Typically (but not always), the subject of a clause performs an action, and the direct object is acted upon by the subject: Jake [subject] baked [transitive verb] a cake [direct object].
