KK: /ˈkʌfˌlɪŋk/
A decorative fastener used to secure the cuffs of a dress shirt.
He wore a pair of elegant cufflinks to the formal event.
Cufflink → The word is formed from "cuff" (from Middle English *cuffe*, meaning the end of a sleeve) and "link" (from Old English *hlinc*, meaning a connection or fastening). A cufflink is a fastening that connects the cuffs of a shirt.
Think of a 'cuff' as the end of a sleeve that needs to be 'linked' together — that's why a cufflink is used to fasten shirt cuffs.
