wynn
/wɪn
/(also wyn)
noun
A runic letter, used in Old and Middle English, later replaced by w.The modern English wine comes from Old English wn, pronounced like modern ‘wean’: that indeed was how Chaucer pronounced his wyn, but Shakespeare's pronunciation was closer to our own.
Origin
Old English, literally 'joy'; so named because it is the first letter of this word. Compare with thorn (sense 3) and ash2 (sense 2).
