Well uisce is the Irish Gaelic for water, beatha means lively. Which taken together mean Whisky! Or to be more accurate Uisce Beatha really means Whiskey, as uisce beatha is the Irish Gaelic, its Scottish counterpart is uisge beatha.
Both are derived from aqua vitae the latin for Water of Life and the mispronunciation/Anglicisation of Uisce is the origin of our word Whisky/Whiskey. It’s also the inspiration for the Anonymous 19th Century Street Ballad which was inspired James Joyce’s experimental and much criticised novel of the same name Finnegan’s Wake. The Ballad plays upon the dual meanings of wake, that being a traditional wake or send off for a lost relative and the act of rousing. Over the course of the ballad a lively wake is held, during which a fight breaks out. As a result uisce beatha or water of life splashes upon the corpse causing him to revive, shocked to learn the attended believed him dead.
