Wales /ˈweɪlz/ (Welsh: Cymru; pronounced [ˈkəmrɨ] ) is a country that is part of the United Kingdom of Great Britain and Northern Ireland, bordered by England to its east, and the Atlantic Ocean and Irish Sea to its west. Wales has a population estimated at three million and is officially bilingual; both Welsh and English have equal status and bilingual signs are the norm throughout the land. For most people in Wales, English is their only language. The once-steady decline in Welsh speaking has reversed over recent years, however, with Welsh speakers currently estimated to be around 20% of the population.
The English name Wales originates from the Germanic words Walh (singular) and Walha (plural), meaning "foreigner" or "stranger". The Ænglisc-speaking Anglo-Saxons used the term Waelisc when referring to the Celtic Britons, and Wēalas when referring to their lands.
The modern Welsh name for themselves is Cymry, and Cymru is Welsh for "Land of the Cymry". The etymological origin of Cymry is from the (reconstructed) Brythonic word combrogi, meaning "compatriots", in the sense of "fellow countrymen"
