A grammatical case is a category of nouns and noun modifiers (determiners, adjectives, participles, and numerals), which corresponds to one or more potential grammatical functions for a nominal group in a wording. In various languages, nominal groups consisting of a noun and its modifiers belong to one of a few such categories.
