1911 Encyclopædia Britannica/Aiguillette
AIGUILLETTE (Fr. diminutive of aiguille, a needle; the obsolete English form is “aglet“), originally a tag of metal, often made of precious metals and richly chased, attached to the end of a lace or ribbon, and pointed, so as to pass more easily through eyelet holes. The term was, in time, applied to any bright ornament or pendant for the dress made of metal, and is now specially used of ornamental cords and tags of gold and silver lace, worn on naval and military uniforms. The aiguillette is fastened to the shoulder, the various cords hanging down therefrom being fastened at their other end on the front of the coat.
