A grammatical case is a category of nouns and noun modifiers that 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. For instance, in English, one says I see them and they see me: the nominative pronouns I/they represent the perceiver and the accusative pronouns me/them represent the phenomenon perceived. Here, nominative and accusative are cases, that is, categories of pronouns corresponding to the functions they have in representation.

English is a West Germanic language in the Indo-European language family, whose speakers, called Anglophones, originated in early medieval England. The namesake of the language is the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain.
