Yule: [OE] Old English gēol, the ancestor of modern English Yule, was originally the name of a pre-Christian mid-winter festival, but it later came to be applied to ‘Christmas’. It was related to Old Norse jól ‘mid-winter festival’ (possible source of English jolly), but where it ultimately came from is not known. It has been speculated that it may be descended from the Indo- European base *qwelo- ‘go round’ (source of English cycle and wheel), in which case it would denote etymologically the ‘turn’ of the year.
yuppie: [20] Yuppie is an acronym, formed in the USA from the initial letters of ‘young urban professional’. It came on the scene in 1984, and at first competed with yumpie (formed from ‘young upwardly mobile people’). It was yuppie which won out, and indeed has thrived to such an extent as to produce a whole range of (more or less ephemeral) clones such as buppie ‘black yuppie’, guppie ‘green [ecologically concerned] yuppie’, and Juppie ‘Japanese yuppie’.
a late-developing letter in English. Called ipsilon in German, upsilon in Greek, the English name is of obscure origin. The sound at the beginning of yard, yes, yield, etc. is from Old English words with initial g- as in got and y- as in yet, which were considered the same sound and often transcribed as Ȝ, known as yogh. The system was altered by French scribes, who brought over the continental use of -g- and from the early 1200s used -y- and sometimes -gh- to replace Ȝ. As short for YMCA, etc., by 1915.
