This document discusses language planning, which involves deliberate efforts to influence or change aspects of language use within a community. There are three main types of language planning: status planning determines a language's social functions and prestige; corpus planning focuses on structural changes through standardization and modernization; and acquisition planning aims to change how languages are learned. The goals and ideologies behind language planning vary but often include selecting an official language, developing writing systems, expanding vocabulary, and increasing a language's social domains and number of speakers. Effective language planning requires addressing issues of language rights and obtaining reliable linguistic data.
