Language authorities are organizations or individuals that provide guidance on the correct use of a language. They establish rules for grammar, spelling, and pronunciation, helping to maintain consistency and clarity in communication. Examples of language authorities include the Académie Française for French and the Oxford English Dictionary for English. These authorities often publish style guides, dictionaries, and other resources to assist writers, educators, and the general public. They may also engage in debates about language evolution, addressing how new words and usages should be accepted or regulated.
