Etymology
Another possible connection of vodka with water is the name of the medieval alcoholic beverage aqua vitae (Latin, literally, 'water of life'), which is reflected in Polish okowita, Ukrainian оковита, Belarusian акавіта, and Scandinavian akvavit. Whiskey has a similar etymology, from Irish and Scottish Gaelic uisce beatha / uisge-beatha.
