Определение и Значение "benefactive case"

What is the "benefactive case"?

The benefactive case is a grammatical case used to indicate the benefit or advantage of an action for someone or something. It often expresses the idea of "for" or "on behalf of" in relation to a noun. This case is found in languages such as Hungarian and Finnish, where it modifies nouns to show for whom an action is performed. For example, in Hungarian, the word for "child" is "gyerek," and in the benefactive case, it changes to "gyereknek," meaning "for the child." The benefactive case helps clarify who receives the benefit of an action in a sentence.
