Language
The United Kingdom has no official language. English is the main language and the de facto official language, spoken monolingually by an estimated 95% of the UK population.

However, some nations and regions of the UK have frameworks for the promotion of indigenous languages. In Wales, English and Welsh are both widely used by officialdom, and Irish and Ulster Scots enjoy limited use alongside English in Northern Ireland, mainly in publicly commissioned translations. Additionally, the Western Isles council area of Scotland has a policy to promote Scottish Gaelic.

Under the European Charter for Regional or Minority Languages, which is not legally enforceable, the UK Government has committed itself to the promotion of certain linguistic traditions. Welsh, Scottish Gaelic and Cornish are to be developed in Wales, Scotland and Cornwall respectively. Other native languages afforded such protection include Irish in Northern Ireland, Scots in Scotland and Northern Ireland, where it is known in official parlance as "Ulster Scots" or "Ullans" but in the speech of users simply as "Scotch", Broad Scots, and British Sign Language.
