See Equatorial Guinea#Languages.


Significant minority language
Though not an official language at the national level, Spanish is regularly spoken by significant minority populations in each of the nations and territories noted below. In each, public services and information are widely available in Spanish, as are various forms of printed and broadcast media.


Andorra

The Spanish language is not official but also holds a special status (in the education system, the media, and some official documents) in the Principality of Andorra which shares land borders with Spain.[24]
Belize

Spanish has no official recognition in the Central American nation of Belize, a Commonwealth realm where English is the official national language. However, the country shares land borders with Spanish-speaking Mexico and Guatemala and, per the 2010 Belizean census, Spanish is spoken by a sizable portion of the population; 30% claim Spanish as a mother tongue and about 50% of the population has working knowledge of the language.[25]
Gibraltar

The Spanish language is not official but also holds a special status (in the education system, the media, and some official documents) in the British Overseas Territory of Gibraltar, which share land borders with Spain.[26]
United States

Spanish has been spoken in the United States for several centuries in the Southwest and Florida, which were all once part of New Spain. However, today only a tiny minority of Spanish speakers in the US trace their language back to those times; the overwhelming majority of speakers come from recent immigration. Only in northern New Mexico and southern Colorado has Spanish maintained speaking communities uninterruptedly since colonial times. [27] Spanish is the most studied foreign language in United States schools and is spoken as a native tongue by 41 million people, plus an additional 11 million fluent second-language speakers.[28] Though not official, Spanish has a special status for education in the U.S. state of New Mexico. [29] With over 50 million native speakers and second language speakers, the United States now has the second largest Spanish-speaking population in the world after Mexico.[30] Spanish is increasingly used alongside English nationwide in business and politics. In the United States, the language is regulated by the North American Academy of the Spanish Language.
Historical language
Philippines


Spanish was an official language of the Philippines from the beginning of the Hispanic period in 1565 and through independence until a constitutional change in 1973. 
However, President Ferdinand Marcos had Spanish redesigned as an official language under Presidential Decree No. 156, dated 15 March 1973 and Spanish remained official until 1987, when it was re-designated as a voluntary and optional auxiliary language.[31]
On 8 August 2007, President Gloria Macapagal-Arroyo announced that the Philippine government asked help from the Spanish Government in her plan to reintroduce Spanish as a required subject in the Philippine school system.[32] By 2012, the language was a compulsory subject at only a very select number of secondary schools.[33] In spite of government promotion of Spanish, less than 0.5% of the population are able to speak Spanish at least proficiently.[34]
While Spanish is designated as an optional government language in the Philippines, its usage is very limited and not present in everyday life.[35] In the country, Spanish is regulated by the Philippine Academy of the Spanish Language.
Western Sahara
Spanish is a secondary official language, alongside Arabic, in the Sahrawi Arab Democratic Republic, a former Spanish colony and now a partially recognized state, most of whose territory is occupied by Morocco. Spanish is not a native language in that country.[36][37]
Creole languages

There are a number of Spanish-based creole languages. Chavacano is spoken in Zamboanga City in the Philippines and is a regional language.[38] Papiamento is the official language in Aruba, Bonaire and Curaçao; it has been classified as either a Spanish-based or a Portuguese-based creole.[39][40]
Chamorro is an Austronesian language with many Spanish loanwords; some scholars have considered it a creole, but the most authoritative sources deny this.[41]

Judeo-Spanish

Judaeo-Spanish (sometimes known as Ladino or other names) is a language derived from medieval Spanish; it is still spoken by some Sephardi Jews, mainly in Israel.[48]
