British slang

While some slang words and phrases are used throughout Britain (e.g. knackered, meaning "exhausted"), others are restricted to smaller regions, even to small geographical areas. The nations of the United Kingdom, which are England, Scotland, Wales and Northern Ireland, all have their own slang words, as does London. Cockney slang has many varieties, the best known of which is rhyming slang.

British slang has been the subject of many books, including a seven volume dictionary published in 1889. Lexicographer Eric Partridge published several works about British slang, most notably A Dictionary of Slang and Unconventional English, revised and edited by Paul Beale.

Many of the words and phrases listed in this article are no longer in current use.
