The word "buckle" traces back to the Old French "boucle," meaning "a boss (protruding ornament) or ring," derived from Latin "buccula" (little cheek or mouthpiece of a helmet). Over time, it evolved to denote a clasp mechanism. The suffix "-le" may imply a diminutive or repetitive action (e.g., bending or fastening). The dual meanings—fastening and bending—reflect the object's functional and physical properties.
