A small decorative item used to fasten a scarf or tie securely in place.
She wore a beautiful scarfpin that matched her outfit perfectly.
Scarfpin → It is formed from "scarf" (from Old Norse *skarf*, meaning a piece of cloth or garment) and "pin" (from Old English *pinn*, meaning a small pointed object used for fastening). The word "scarfpin" refers to a pin used to fasten a scarf or piece of cloth.
Think of a 'piece of cloth' ('scarf') being held together by a 'pointed object' ('pin') — that's what a scarfpin does.
