Louchebem Language

Encryption replaces the words by changing them applying successively some rules:

- Move the first consonant or syllable in the end of the word.

Example: BOUCHER becomes OUCHERB

- Insert the letter L at the beginning of the word

Example: OUCHERB becomes LOUCHERB

- Add a syllable slang at the end, usually -ji, -oc, -euil, -uche, -ès, or -em

Example: LOUCHERB becomes for example LOUCHERBEM

As the language of butchers is primarily a spoken language it allows many simplifications

Example: LOUCHERBEM was shortened to LOUCHEBEM (phonetically)

Decryption is to undo the changes by encryption to find the original words:

- Delete the added final syllable

Example: LOUCHERBEM becomes LOUCHERB

- Remove the initial L

Example: LOUCHERB becomes OUCHERB

- Move the letter or the final syllable at the beginning

Example: OUCHERB becomes BOUCHER.

The message contains many words beginning with L and the final syllable is sounding like (french?) slang: -ji, -oc, -ic -uche, -ès or -em.

Le Louchebem is similar to verlan.

There is no rule, it is preferable that the word has a good sound and be pronounceable.

Loucheben finds its first traces in the mid 19th century, and perhaps not by butchers. It was later popularized in Lyon and Paris (France)
