Louchébem

Louchébem is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Louchébem rather than just read about it. In short: Louchébem or loucherbem (French pronunciation: [luʃebɛm]) is Parisian and Lyonnaise butchers' (French boucher) slang, similar to Pig Latin and Verlan. It originated in the mid-19th century and was in common use until the 1950s.

Key takeaways

Louchébem belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Louchébem to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Louchébem from memory before moving on to harder problems.

Reference excerpt

Louchébem or loucherbem (French pronunciation: [luʃebɛm]) is Parisian and Lyonnaise butchers' (French boucher) slang, similar to Pig Latin and Verlan. It originated in the mid-19th century and was in common use until the 1950s.

Process The louchébem word-creation process resembles that of largonji, verlan, and javanais, in that existing words are camouflaged according to a set of rules. Strictly speaking, louchébem is a more rigid variety of largonji in which the ending -èm is obligatory. Largonji substitutes ⟨l⟩ for the consonant or consonant cluster at the beginning of the word, or, if the word begins with an ⟨l⟩ or a vowel, the second syllable; the initial consonant is then reattached to the end of the word along with a suffix particular to the argot: -ji [ʒi], -oc [ɔk], -ic [ik], -uche [yʃ], -ès [ɛs], or in the case of louchébem, -em/ème [ɛm]. Note that louchébem is first and foremost an oral language, and spelling is usually phoneticized.

History Despite the name, louchébem seems to have been created not by butchers, but by inmates at Brest Prison, with records dating back to 1821. Edmund Clerihew Bentley used the language as a plot point in his 1937 short story "The Old-Fashioned Apache". During the Nazi occupation louchébem was used by Parisian members of the Resistance. Even today, louchébem is still well-known and used among those working at point-of-sale in the meat retail industry. Some words have even leaked into common, everyday use by the masses; an example is the word loufoque, meaning "eccentric".

Examples Here are a few example Louchébem words.

There is another French argot called largonji, which differs from louchébem only in the suffix that is added (-i instead of -em); the term is derived from jargon.

Worked examples

Example 1 — a first encounter with Louchébem

Start with the simplest possible case. Write down what Louchébem claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Louchébem before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Louchébem ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Louchébem

In research: Louchébem appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Louchébem in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Louchébem is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cant languages, French slang, Language games, so understanding it makes those chapters shorter.
In everyday life: Look for Louchébem outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
