Portuguese language in Africa: Portuguese is spoken in a number of African countries and is the official language in six African states: Angola, Mozambique, Guinea-Bissau, Cape Verde, São Tomé and Príncipe and Equatorial Guinea.  There are Portuguese-speaking communities in most countries of Southern Africa, a mixture of Portuguese settlers and Angolans and Mozambicans who left their countries during the civil wars.  A rough estimate has it that there are about 14 million people who use Portuguese as their sole mother tongue across Africa, but depending on the criteria applied, the number might be considerably higher, since many Africans speak Portuguese as a second language, in countries like Angola and Mozambique, where Portuguese is an official language, but also in countries like South Africa and Senegal, thanks to migrants coming from Portuguese speaking countries.  Some statistics claim that there are over 30 million Portuguese speakers in the continent.  Like French and English, Portuguese has become a post-colonial language in Africa and one of the working languages of the African Union (AU) and the Southern African Development Community (SADC).  Portuguese co-exists in Guinea-Bissau, Cape Verde, and São Tomé and Principe with Portuguese-based creoles (Upper Guinea and Gulf of Guinea Creoles), and in Angola, Mozambique, and Guinea-Bissau with autochthonous African languages (mainly Niger–Congo family languages).

Greenlandic language is the official language on Greenland and Greenland's Home Rule Act of 2009 does not require Danish to be taught or the use of Danish for official purposes.

Bihari languages: Bihari is the western group of Eastern Indo-Aryan languages, spoken in Bihar, Uttar Pradesh and neighboring states in India.  Angika, Awadhi, Bajjika, Bhojpuri, Magahi, and Maithili are spoken in Nepal as well.  The Angika, Awadhi, Bajjika, Bhojpuri, Magahi and Maithili speaking population form more than 21% of Nepalese population.  Despite the large number of speakers of these languages, they have not been constitutionally recognised in India, except Maithili, which gained constitutional status via the 92nd amendment to the Constitution of India, of 2003 (gaining assent in 2004).  Even in Bihar, Hindi is the language used for educational and official matters.  These languages were legally absorbed under the overarching label Hindi in the 1961 Census.  Such state and national politics are creating conditions for language endangerments.  After independence Hindi was given the sole official status through the Bihar Official Language Act, 1950.  Hindi was displaced as the sole official language of Bihar in 1981, when Urdu was accorded the status of the second official language.  In this struggle between Hindi and Urdu, the claims of widely-spoken native languages of the region—namely, Angika, Maithili, Bhojpuri, and Magahi—were ignored.

Portuguese-speaking African countries: The Portuguese-speaking African countries (also referred to as Lusophone Africa) consist of six African countries in which the Portuguese language is an official language: Angola, Cape Verde, Guinea-Bissau, Mozambique, São Tomé and Príncipe and, since 2011, Equatorial Guinea.  The six countries are former colonies of the Portuguese Empire.  From 1778 until independence, Equatorial Guinea was also a colony of the Spanish Empire.  In 1992, the five Lusophone African countries formed an interstate organisation called PALOP, a colloquial acronym that translates to African Countries of Portuguese Official Language (Portuguese: "Países Africanos de Língua Oficial Portuguesa" ).  The PALOP countries have signed official agreements with Portugal, the European Union and the United Nations, and they work together to promote the development of culture and education and the preservation of the Portuguese language.  Together with Portugal and Brazil in 1996, the Portuguese-speaking African countries established the Community of Portuguese Language Countries (Portuguese: "Comunidade dos Países de Língua Portuguesa" , abbreviated to CPLP), which East Timor later joined in 2002 and Equatorial Guinea in 2014.
