🎤Pronunciation
🌳Etymology
Origin
The word derives from 16th-century French 'buffle' (buffalo), referring to buffalo hide. Polishing cloth made from this durable leather was called 'buff' and used to burnish weapons and tools to a shine. The sense 'enthusiast' emerged in the 19th century from the bright buff-colored uniforms worn by volunteer firefighters, initially referring to fire enthusiasts before generalizing to any devoted fan.
Breakdown
buffle (French for buffalo) → buff (buffalo leather; to polish/shine) → buff (devotee, enthusiast). The modern 'enthusiast' sense stems from metonymy: the distinctive buff-colored uniforms of 19th-century firefighters became associated with their passionate devotion.
