Word Origin and History for w

W


not in the Roman alphabet, but the Modern English sound it represents is close to the devocalized consonant expressed by Roman -U- or -V-. In Old English, this originally was written -uu-, but by 8c. began to be expressed by the runic character wyn (Kentish wen), which looked like this: ƿ (the character is a late addition to the online font set and doesn't display properly on many computers, so it's something like a cross between lower-case -p- and a reversed -y-). In 11c., Norman scribes introduced -w-, a ligatured doubling of Roman -u- which had been used on the continent for the Germanic "w" sound, and wyn disappeared c.1300. -W- is not properly a letter in the modern French alphabet, and it is used there only in borrowed foreign words, e.g. wagon, weekend, Western, whisky, wombat.
