An item or object that is displayed to show its quality or importance, often used as an example of the best in its category.
The artist created a stunning showpiece for the gallery's opening night.
Showpiece → It is formed from "show" (from Old English "sceawian", meaning to look at or display) and "piece" (from Old French "piece", meaning a part or fragment). A showpiece is a part or item that is displayed to attract attention or admiration.
Think of something that is 'displayed' ('show') as a 'part' ('piece') of a collection — that's why a showpiece is an item meant to be admired.
