Dear Dr. Vinny,
Where does the word "wine" come from?

Dear Jose,
Let me put on my etymology hat. And pay attention, because there are plenty of crossword answers below.
"Wine" comes from the Old English word "win" (which is pronounced like "wean"). The Old English form was descended from the Latin "vinum," or as the Romans wrote it, "VINVM." "Vinum" in Latin seems to be related to the Latin word for vineyard, "vinea." But I've also read that "vinum" can mean "vine" in Latin too. If that's not far back enough for you, it appears that this Latin version was based on non-Indo-European languages such as Arabic, and their word "wain," or the Hebrew word "Yayin."
Now, it's not clear if the Latin to Old English was a direct line; it could also be a variation of a word that seems to be present in all Germanic languages. (Etymologists must argue about this all the time.) There's the German word "wein," Icelandic "vin" and so on. But the Germans and Celts were native beer drinkers, so they probably got the word from the Romans.
Many also believe that it comes from the Greek word "oinos," from the Greek god of wine, Dionysus.
Perhaps the most interesting tidbit from my research? The term "wine snob" was first recorded in 1951.
