IPA: /ˈɑːrmlɪt/
KK: /ˈɑrmlɪt/
A decorative band or piece of clothing worn around the upper arm, often for style or identification.
She wore a beautiful armlet made of silver and gemstones at the party.
Armlet is formed from "arm" (from Old English "earm", meaning the upper limb) and "-let" (a diminutive suffix meaning small or little). The word "armlet" refers to a small arm ornament or a small arm.
Think of a small version of an 'arm' — the '-let' means little, so an armlet is a little ornament for the arm.
