Source etymology 2

Original entry ↗
noun

Synonym of gonorrhea.

Selected source glosses provide context, not a complete modern definition inventory

Uncertain. Probably from Old French clapoir (“bubo, inflammation from infection”), from clapier (“brothel”). May also be from old, unsafe treatments for gonorrhea, such as clapping the penis between a book and a hard surface to break up obstructions in the urethra and permit urination. Attested from the 16th century.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
