The originatl meaning of 'stay' has been a type of reenforcement to help a metal sheet 'stay' in a position so as not to permit extreme movement of the sheet. Rod or strap could be bolted, riveted, or welded from structure to sheet to hold the metal in place to maintain the design shape at pressure. This might be often used to permit higher pressures than could be achieved by unrestrained surfaces.
A woman of the early period would have used whale-bone for the corset-stay.
