abeilardiser

An obsolete, grimly humorous 19th-century slang verb meaning "to castrate" — a direct historical reference to the medieval scholar Peter Abelard, who was castrated on the orders of Canon Fulbert after his affair with Héloïse became known. It's a period curiosity in old slang dictionaries today, not a word anyone uses.

• Les vieux dictionnaires d'argot citent le verbe abeilardiser. — Old slang dictionaries cite the verb abeilardiser.
• Ce mot rappelle le sort tragique d'Abélard. — This word recalls Abelard's tragic fate.
• Un terme d'argot du XIXe siècle, aujourd'hui disparu de l'usage. — A 19th-century slang term, now vanished from use.

There's nothing to "get wrong" with a word this obsolete — it's included here purely for completeness, and a learner will never need or hear it in real French.
