Outwear → It is formed from "out-" (meaning outside) and "wear" (from Old English "werian", meaning to carry or to wear). The word "outwear" means to wear something out or to use it until it is no longer usable, often implying that it has been worn outside or extensively.
Think of wearing something 'outside' ('out-') until it is no longer usable — that's what outwear means.
