Language planning is typically undertaken with the goal of promoting the use of a particular language or set of languages, often for political, economic, or cultural reasons.

Language policies can include a variety of measures, such as the official language of a country, the language of instruction in schools, the language used in government documents, and the promotion of a particular language through media and cultural programs.

Language revitalization is the process of reviving a language that is no longer spoken, typically through efforts to teach the language to new speakers and promote its use in various domains.

Language standardization is the process of developing a standard variety of a language, typically based on the prestige dialect or the dialect used in government and education.

Language planning initiatives often face a number of challenges, including the resistance of speakers to change their language habits, the lack of resources for language planning initiatives, and the political and economic factors that influence language use.

Language planning can have a number of benefits, including the promotion of social cohesion, the preservation of cultural heritage, and the facilitation of economic development.

There are a number of examples of successful language planning initiatives, including the revival of Hebrew as a spoken language, the standardization of Mandarin Chinese, and the promotion of English as a global lingua franca.

Linguists play a variety of roles in language planning, including providing expert advice on language-related issues, developing language policies and programs, and implementing language planning initiatives.

Language planning initiatives must take into account a number of ethical considerations, including the right of speakers to use their own language, the need to promote social cohesion, and the importance of preserving cultural heritage.

It is impossible to predict the future of language planning, as it will depend on a number of factors, including the changing global political and economic landscape, the development of new technologies, and the changing attitudes of speakers towards language.
