Welsh (y Gymraeg) is a Brythonic branch of Celtic spoken natively in the part of Britain known as Wales (Cymru), and in Trevelin, a Welsh immigrant colony in the Patagonia region of Argentina. There are also many speakers of Welsh in England, the US and Australia.
The usual estimate given for the number of Welsh speakers in Wales is 20% (out of a population of about 3 million). Although a minority language, and thus threatened by the dominance of English, support for the language grew during the second half of the twentieth century, coterminously with the rise of Nationalist political organisations such as Plaid Cymru and Cymdeithas yr Iaith Gymraeg (the Welsh Language Society).
Welsh is very much a living language. It is used in conversation everyday, and seen in Wales everywhere. Local government (including the Welsh assembly) uses Welsh as its official language, public bodies issue official literature and publicity in Welsh versions (e.g. letters to parents from schools, library information, council information) and all road signs in Wales are in English and Welsh, including the Welsh versions of place names (sometimes made after the English names).
A section on the history and development of the language would be nice here!
A section on grammar and structure here would be nice!
A sample of writen Welsh and some pronunciation examples here by a Welsh speaker would be nice!
