Definition: A warning shouted out the window, typically before waste water or otherwise undesirable liquid was thrown out into the street. It is now used as an interjection, but in familiar speech was once used as a noun.
Pronunciation: garh- di-lu
From the French phrase, “Garde de l’eau!” or possibly “Gardez l’eau!” which means “Look out for the water!” It was a common phrase in Edinburgh, Scotland and is theorized to be the origin of the word “loo”.
Why this word: This word appeals to me because of the realistic portrayal of life in cities before plumbing. While it is not uncommon for people to romanticize “olden times”, the reality of life was that people were much more familiar with disease and waste than we are today. On a personal note, as the mother of a young toddler, the idea of someone having to duck to avoid waste water seems more like a fact of daily life than a remnant of historic city life.
