Linguistic purism is the belief in maintaining the traditional forms and structures of a language, often resisting changes brought about by external influences, such as foreign languages or slang. Purists advocate for the preservation of a language's original grammar, vocabulary, and pronunciation, viewing these elements as essential to cultural identity. This movement can be seen in various languages, including French, where purists promote the use of Académie Française approved terms over anglicisms. Linguistic purism often sparks debates about language evolution, as critics argue that languages naturally change over time and that adaptation can enrich a language rather than diminish it.
