Roman alchemists loved a dramatic name, and aqua got promoted from plain old water to something far more dangerous. In medieval Latin, aqua vitae was the "water of life," a phrase that wandered into Gaelic as uisge beatha and eventually came out in English as whiskey — so your cocktail glass has a little Latin in its family tree. Then there was aqua regia, "royal water," the acid mix so fierce it could dissolve gold, as if humble water had put on a crown and turned tyrant. The same watery root keeps turning up in everyday words like aquatic, aquarium, and aqueduct, all of them carrying the same old splash from PIE *akwa-. By the 20th century, aqua had even become a color word, a cool blue-green you can practically see shimmering on a hotel brochure, proof that water never really stays just water.
