A type of wire that is sewn into the bottom of a bra to provide support and shape.
She prefers bras with underwire for extra support.
Underwire → It is formed from "under" (from Old English "under", meaning beneath or below) and "wire" (from Old English "wir", meaning a thin, flexible strand of metal). The word "underwire" refers to a type of support that is placed beneath fabric, typically in bras, to provide shape and support.
Think of something that provides support from 'beneath' ('under') using a 'thin strand of metal' ('wire') — that's what underwire does.
