Linguistic rights (or language rights or linguistic human rights) are the human and civil rights concerning the individual and collective right
to choose the language or languages for communication in a private or
public atmosphere. Other parameters for analyzing linguistic rights
include the degree of territoriality, amount of positivity, orientation
in terms of assimilation or maintenance, and overtness.
Linguistic rights include, among others, the right to one's own
language in legal, administrative and judicial acts, language education,
and media in a language understood and freely chosen by those
concerned.
Linguistic rights in international law are usually dealt in the broader framework of cultural and educational rights.
Important documents for linguistic rights include the Universal Declaration of Linguistic Rights, the European Charter for Regional or Minority Languages and the Framework Convention for the Protection of National Minorities, as well as the International Covenant on Civil and Political Rights.
