a TRANSITIVE VERB is a verb (action word) that requires a direct object.

• he cries. cry is not transitive because it can stand on its own already.

• he drinks. drink is transitive because you’d say “drink what?” it can’t stand on its own. therefore you add a direct object >> he drinks pizza juice.

• she feeds. feed is transitive because you have to say what of who is being fed. >> she feeds the fetus.

a DIRECT OBJECT is the receiver of the action.

• my dad loves the maid. “the maid” is direct object because she’s the one being loved.

• the koala chewed the giraffe’s neck. “giraffe’s neck” is the object because it’s the one being chewed.

• the killer killed the noisy doll. “the noisy doll” is the direct object because it was the one killed.

am sorry i can’t define more (the blahblah part didn’t help)

i hope the above explanations helped you in anyway.

good luck in that presentation.!
