This document gives the general principles for language registers in both descriptive and prescriptive
environments. It defines key concepts and describes examples of different language registers that can
be applied across all or many languages and those that are language-specific. It lays down guidelines
for the use of appropriate language registers needed in a wide range of environments. These include:
— terminology work, where it contributes to the development of a wide range of standards;
— translation, so that appropriate language levels can be chosen in target languages, to match that of the source language;
— lexicography, to improve descriptors of non-geographic language variants;
— second language teaching and learning, so that students can avoid pitfalls associated with
inappropriate language use;
— software, to improve tagging of language variants in computer applications.
