In other languages, the accusative case's main function is to
show the direct object of a verb.
In modern English, it is indistinguishable from the dative case, whose main role in other languages is to show the indirect
object of verb. In English, the objective case
covers the roles of both the accusative case and the dative case.
Examples:
Give
the large parcel to the lady next door.
