What register of language do you intend to use?

The late Qing also saw a "revolution in poetry" (诗界革命), which promoted experimentation with new forms and the incorporation of new registers of language.

The Aztecs distinguished between at least two social registers of language: the language of commoners (macehuallahtolli) and the language of the nobility (tecpillahtolli).

Because of the proposal by Tymoteusz Król, who was 14 years old in that time, the Library of Congress added the Vilamovian language to the register of languages on July 18, 2007.
