Definition
In grammar, 'accusative' is a case that indicates the direct object of a verb. It shows what receives the action. Think of it like this: in the sentence 'The dog chases the ball,' 'ball' is in the accusative case because it's what the dog is chasing. It's directly affected by the verb. Unlike nominative (the subject performing the action), accusative highlights the receiver. It is the target of the action.
