Question: In how many states of the Member states of the Commonwealth of Nations is English either spoken as first or second language or at least widely used?
Context: Fiji has three official languages under the 1997 constitution (and not revoked by the 2013 Constitution): English, Fijian and Hindi.  Fijian is spoken either as a first or second language by indigenous Fijians who make up around 54% of the population.  Fijians of Indian descent make up a further 37%, mainly speaking a local variant of Hindi, known as "Fiji Hindi".  English, a remnant of British colonial rule over the islands, was the sole official language until 1997 and is widely used in government, business, and education as a lingua franca; considerable business is also done in Fijian, especially away from larger town centre. Irish Sign Language (ISL, Irish: "Teanga Chomharthaíochta na hÉireann" ) is the sign language of Ireland, used primarily in the Republic of Ireland.  It is also used in Northern Ireland, though British Sign Language (BSL) is also used there.  Irish Sign Language is more closely related to French Sign Language (LSF) than to British Sign Language, though it has influence from both languages.  It has influenced sign languages in Australia and South Africa, and has little relation to either spoken Irish or English. The Commonwealth of Nations is a voluntary association of 52 sovereign states.  Nearly all of them are former British colonies or dependencies of those colonies. Roviana is a member of the North West Solomonic branch of Oceanic languages.  It is spoken around Roviana and Vonavona lagoons at the north central New Georgia in the Solomon Islands.  It has 10,000 first-language speakers and an additional 16,000 people mostly over 30 years old speak it as a second language (Raymond 2005).  In the past, Roviana was widely used as a trade language and further used as a lingua franca especially for church purposes in the Western Province but now it is being replaced by the Solomon Islands Pijin.  Few published studies on Roviana language include: Ray (1926), Waterhouse (1949) and Todd (1978) contain the syntax of Roviana language. The use of the English language in most member countries of the Commonwealth of Nations was inherited from British colonisation.  English is spoken as a first or second language in most of the Commonwealth.  In a few countries, such as Cyprus and Malaysia, it does not have official status, but is widely used as a lingua franca.  Mozambique is an exception – although English is widely spoken there, it is a former Portuguese colony which joined the Commonwealth in 1996. Language attrition is the process of losing a native, or first, language.  This process is generally caused by both isolation from speakers of the first language and the acquisition and use of a second language, which interferes with the correct production and comprehension of the first.  Such interference from a second language is likely experienced to some extent by all bilinguals, but is most evident among speakers for whom a language other than their first has started to play an important, if not dominant, role in everyday life; these speakers are at a higher risk for experiencing language attrition.  A notable example of this is found in immigrants, who may move to a country in which a language foreign to them is spoken, and go on to use that later-learned environmental language in their daily lives.  Their gradual decline in proficiency in their first language, or L1, resulting from both isolation from other speakers of their L1 and interference from the L2 they are acquiring, is considered language attrition. Commonwealth free trade is the process or proposal of removing barriers of trade between member states of the Commonwealth of Nations.  The preferential trade regime within the British Empire continued in some form amongst Commonwealth nations under the Imperial Preference system, until that system was dismantled after World War II due to changes in geopolitics and the pattern of global trade, and the United Kingdom's entry into the European Economic Community.  The idea of promoting renewed inter-Commonwealth trade emerged in the late 20th century as a response to the evolution of the global economy.  At one extreme, proposals have been raised for the creation of a multilateral free trade area comprising all member states of the Commonwealth of Nations. Vivian James Cook (born 13 June 1940) is Emeritus Professor of Applied Linguistics at Newcastle University in the United Kingdom.  He is renowned for his work on second language acquisition and second language teaching, and for writing successful textbooks and popular books about linguistics.  He has worked on a number of topics such as bilingualism, EFL (English as a Foreign Language), first language acquisition, second language teaching, linguistics, and the English writing system.  He has published more than 20 books and 100 papers.  He was founder and first President of the European Second Language Association (EuroSLA), and co-founder of the Oxford University Press journal "Writing Systems Research". The Israeli population is a linguistically and culturally diverse community.  The 19th edition of Ethnologue lists 35 languages and dialects spoken in local communities.  Hebrew, which is one of the country's two official languages, is the primary language of Israel, and almost the entire population speaks it either as native speakers or proficiently as a second language.  Its standard form, known as Modern Hebrew, is the main language used for communication.  Arabic, used mainly by Israel's Arab minority, which comprises about one-fifth of the population, is the country's second official language.  English, spoken as a second language by the majority of the Israeli population, is used widely in official logos, road signs and product labels.  Russian, spoken by the large immigrant population from the former Soviet Union, is also heavily used. The foreign relations of the Republic of China (ROC), known informally and referred to by many states as Taiwan, are the relations between the Republic of China and other countries.  The Republic of China is recognized by  out of 193 United Nations member states, as well as the Holy See.  These diplomatic relations do not constitute an acceptance by these nations of Taiwan as a state but rather represent a recognition of the ROC government as the representative of all of China, including the Chinese mainland.  In addition to these relations, the ROC maintains unofficial relations with 57 UN member states via its representative offices and consulates.
