Words related to wino
Old English win "wine," from Proto-Germanic *winam (source also of Old Saxon, Old Frisian, Old High German win, Old Norse vin, Dutch wijn, German Wein), an early borrowing from Latin vinum "wine," from PIE *uoin-a-, related to words for "wine" in other southern European languages (Greek oinos, Albanian Ghegvênë), also Armenian (gini), Hittite (uiian(a)-), and non-Indo-European Georgian and West Semitic (Arabic wain, Hebrew yayin).
According to Watkins, probably from a lost Mediterranean language word *win-/*woin- "wine." However, Beekes argues that the word is of Indo-European origin, related to Greek itea "willow," Latin vītis "vine," and other words, and they may be derived from the root *wei- "to turn, bend."
As the wild vine was indigenous in southern Russia and in certain parts of central Europe, this assumption is acceptable from a historical point of view. However, as the cultivation of the vine started in the Mediterranean region, in the Pontus area and in the south of the Caucasus, most scholars are inclined to look for the origin of the word in these countries. This would point to non-IE origin. However, if we put the homeland of viticulture in the Pontus and the northern Balkans, the word for 'wine' might come from there. [Beekes]

fifteenth letter of the alphabet, from a character that in Phoenician was called 'ain (literally "eye") and represented "a very peculiar and to us unpronounceable guttural" [Century Dictionary]. The Greeks also lacked the sound, so when they adopted the Phoenician letters they arbitrarily changed O's value to a vowel. (Thus there is no grounds for the belief that the form of the letter represents the shape of the mouth in pronouncing it.) The Greeks later added a special character for "long" O (omega), and the original became "little o" (omicron).
In Middle English and later colloquial use, o or o' can be an abbreviation of on or of, and is still literary in some words (o'clock, Jack-o'-lantern, tam-o'-shanter, cat-o'-nine-tails, will-o'-the-wisp, etc.).
