An official language is a language that is given a special legal status in a particular country, state, or other territory. A language is a dynamic set of visual auditory or tactile Symbols of Communication and the elements used to manipulate them In Political geography and International politics, a country is a Political division of a geographical entity A state is a political association with effective Sovereignty over a geographic Area and representing a Population. Typically a nation's official language will be the one used in that nation's courts, parliament and administration.  However, official status can also be used to give a language (often indigenous) a legal status, even if that language is not widely spoken. For example, in New Zealand the Māori language has official status under the Māori Language Act even though it is spoken by less than five percent of the New Zealand population. New Zealand is an Island country in the south-western Pacific Ocean comprising two main landmasses (the North Island and the South Island The Māori Language Act 1987 was a piece of Legislation passed by the New Zealand Parliament.  Non-national or supra-national organizations such as the United Nations and the European Union may also have official languages. The United Nations ( UN) is an International organization whose stated aims are to facilitate cooperation in International law, International security The European Union ( EU) is a political and economic union of twenty-seven member states, located primarily in
True official languages are those designated as such by a regulation or law, such as the Māori Language Act or the Welsh Language Act 1967.

In some cases only the official language(s) may be used in court, the education system or other settings, whereas in other cases official status merely allows for that language to be used. For example, the Māori Language Act allows Māori to be used in legal settings, but the vast majority of New Zealand legal proceedings are still carried out in English despite English having only de facto official status. In other countries in which the official language is more generally but not universally spoken, such as the Republic of Ireland and Wales, state publications and signage must be available in the official language as well as the dominant language. Ireland ( Irish: Éire, ˈeːrʲə is a country in north-western Europe. Official language status usually increases the likelihood that a language will be widely taught in schools, and in many cases (for example Ireland) the official language is a compulsory subject.

Irish (ga ''Gaeilge'' is a Goidelic language of the Indo-European language family originating in Ireland and historically spoken by the Irish. Irish nationalism (Náisiúnachas Éireannach refers to political and sociological movements and sentiment that embodies a love for Irish ancestry, culture and language and Various indigenous rights movements have sought greater recognition of their languages, often through official language status.
