Largonji is even more similar to pig Latin than verlan, as you can see by its formation. In largonji, the first letter of the word is moved to the end and one of a wide variety of suffixes is attached:
- -é
- -em
- -gue
- -i
- -ic
- -iche
- -oque
- -ot
- -qué
- -uche
For example, let's start with the word jargon, which can mean jargon, lingo, or gibberish. Take the J and put it at the end of the word, then add a suffix - in this case, we'll use -i. Put an L at the beginning of the word and voilà.
jargon... argonj... argonji... largonji
Thus, you have the secret word largonji - the name of this language (jargon in largonji).
Let's try another example: boucher... oucherb... oucherbem... loucherbem - the other name for this language, after the butchers who invented and used it.
Largonji is not an exact science. Letters may be dropped, changed, or added. Some single-syllable words may or may not have a suffix added (fou = louf or loufoque). Largonji is no longer commonly used, although you might hear a word here and there.
Essential Largonji / Loucherbem / Louchébème
Here are some common largonji terms that you might run across. You'll notice that many of the terms have to do with numbers and money - the butchers obviously liked to talk about prices in secret.
