Definitions for "Direct object"
Keywords:  verb, pronoun, noun, transitive, phrase
The simple definition " the thing that is affected by the verb" is crude but often helpful. It's a noun phrase that is connected to (and dependent on) a verb and usually shows where the action of the verb was directed: I've finished my essay. This means that in a syntactic tree the direct object is the sister of the verb. Not all verbs are followed by an object: some stand alone - e.g. I'm resting; others are followed by a prepositional phrase : e.g. She drove up the road.
The word, phrase, or clause that is the primary goal or result of the action of the verb (cf. accusative case); the person or thing is directly affected by the action of the verb. Heb: "God created the heavens and the earth" (Gen. 1:1). Gr: "He grabbed him and began to choke him" (Matt. 18:28).
