Back slang
Back slang is an English coded language in which the written word is spoken phonemically backwards. It is thought to have originated in Victorian England, being used mainly by market sellers, such as butchers and greengrocers, to have private conversations behind their customers' backs and pass off lower quality goods to less observant customers. Some back slang has entered standard English. For example the term 'yob' was originally back slang for 'boy'. The appellation
back slang is specific to the English language. Other languages, however, have similar coded forms, such as the French
verlan, in which it is syllables, rather than the entire word, that are reversed. Lunfardo, a Spanish argot spoken in Argentina, occurs words spoken in
vesre. In some regions, the term
back slang is used more generally for other codings such as the inclusion of extra syllables in the middle of words, such as
heagy peagy and is a main part of the plot in the episode of the BBC Radio 4 comedy series
After Henry occasionally repeated on BBC Radio 7.
