every: [OE] Stripped down into its component parts, every means literally ‘ever each’. It was originally an Old English compound made up of ǣfre ‘ever’ and ǣlc ‘each’, in which basically the ‘ever’ was performing an emphasizing function; in modern English terms it signified something like ‘every single’, or, in colloquial American, ‘every which’. By late Old English times the two elements had fused to form a single word. => each, ever[every etymology, every origin, 英语词源]
