Outlet → It is formed from "out" (meaning outside or away) and "let" (from Old English "lettan", meaning to allow or permit). The word "outlet" refers to a point of exit or a means of allowing something to flow out.
Think of something that allows things to flow 'outside' ('out') — that's why an outlet is a point where something can exit.
