The spirit, from Irish uisce beatha and Scottish Gaelic uisge beatha, water of life, worn down by English mouths until only the water remained.
Documented
The water of life
Documented: uisce beatha is the Gaelic translation of Latin aqua vitae, the standard medieval name for distilled spirits, alongside Scandinavian akvavit and French eau-de-vie, all naming the same invention with the same metaphor. English usquebaugh appears in the sixteenth century, shortening to whisky and whiskey by the eighteenth.
Assessment: Documented: the aqua vitae family is pan-European. The word records the moment distillation felt like immortality.
Stories
The spelling border
The documented shibboleth: whisky in Scotland, Canada, and Japan; whiskey in Ireland and America, the extra e carried by Irish emigrants and kept as a badge. Brands and law codes enforce the distinction to this day, a one-letter border drawn across every bar shelf in the world.
Assessment: Documented: the spelling split maps emigration. The e is a passport.
Interesting claims
The life that leaked out
The pattern: aqua vitae, eau-de-vie, akvavit, uisce beatha, zhiznennaia voda, every culture independently named distilled alcohol living water, because the first distillates were medicine, monastic pharmacy. The word preserves the era when the pharmacy and the tavern were the same room.
Assessment: Interesting: five languages, one metaphor, zero coordination. The archive files the agreement as evidence about the distillers, not the water.

Worth asking
What happened to the beatha, and what does it say that the water is what survived?
