Welsh (Cymraeg or y Gymraeg, pronounced [kəmˈrɑːɨɡ, ə ɡəmˈrɑːɨɡ]) is a member of the Brythonic branch of the Celtic languages spoken natively in Wales, by some along the Welsh border in England, and in Y Wladfa (the Welsh colony in Chubut Province, Argentina). Historically, it has also been known in English as "Cambrian", "Cambric" and "Cymric".

The Welsh Language Board indicated in 2004 that 611,000 people (21.7% of the population of Wales in households or communal establishments^{[clarification needed]}) were able to speak the language. This figure marks a 0.9 percentage point increase when compared with a figure of 20.8% from the 2001 census, and an increase of approximately 35,000 in absolute numbers within Wales. Of those 611,000 Welsh speakers, 57% (315,000) considered themselves fluent, and 78% (477,000) consider themselves fluent or "fair" speakers. 62% of speakers (340,000) claimed to speak the language daily, including 88% of fluent speakers.

A greeting in Welsh is one of 55 languages included on the Voyager Golden Record chosen to be representative of Earth in NASA's Voyager program launched in 1977. The greetings are unique to each language, with the Welsh greeting being Iechyd da i chwi yn awr ac yn oesoedd which translates into English as "Good health to you now and forever".

Ali G (born Alistair Leslie Graham) is a satirical fictional character created and performed by English comedian Sacha Baron Cohen. Originally appearing on Channel 4's Eleven O'Clock show, as the title character of Channel 4's Da Ali G Show in 2000 and on HBO in 2003–2004, he is also the title character of the film Ali G Indahouse. Cohen's character Ali G, along with Borat and Brüno, has been retired.

The character of Ali G is a stereotype of a white suburban male from Staines (now Staines-upon-Thames) who imitates rap culture as well as urban British and Jamaican culture, particularly through hip hop, reggae, drum and bass and jungle music. Ali G was part of a group called Berkshire Massif, and he ran and grew up in an area of Slough called Langley (both actual locations in the UK). He also lived part of his life in Staines. Baron Cohen has stated that BBC Radio 1 DJ Tim Westwood was an influence on the development of the Ali G character – Westwood hosts Radio 1's Rap Show and speaks in a faux Multicultural London English and Hip-Hop dialect. Ali G's middle class credentials mirror Westwood's: the latter was brought up in Lowestoft, Suffolk as a bishop's son.
