Languages of the United Kingdom
languages of a geographic region
English is the most widely spoken and de facto official language of the United Kingdom. A number of regional and migrant languages are also spoken. Indigenous Indo-European regional languages include both Celtic languages and Germanic languages. The main Celtic languages are grouped into Goidelic, which includes Irish and Scottish Gaelic; and the surviving Western Brittonic language, Welsh.
Close relatives of English in the West Germanic language group include Scots and Ulster Scots. There are many non-native languages spoken by immigrants and their descendents, including Polish, Hindi, and Urdu. British Sign Language is sometimes used as well as liturgical and hobby languages such as Latin and a Celtic revived form of Southwestern Brittonic, Cornish.
Welsh is spoken by 538,300 people in Wales according to the 2021 census. Data from the Annual Population Survey shows that 28%, or roughly 862,700 people, of Wales' population aged three and over were able to speak the language in March 2024. Welsh is a de jure official language under the Welsh Language (Wales) Measure 2011 in Wales.

Why this record matters
The phrase “languages of a geographic region” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q3217446. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021, 2024 and 2011.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
