casquette (French)
Where does "casquette" come from?
The French word 'casquette' traces its origins back to the Proto-Indo-European root *(s)kweh₁t-, meaning to shake or stir. This concept evolved through the Latin 'quatio' and the Spanish 'casco' (helmet) before entering French as 'casque' and eventually becoming 'casquette' through the addition of a diminutive suffix to describe a small cap.
