The Spanish for “throat” garganta sounds completely unrelated to any similar word in English.
But it is actually a close cousin of both gargoyle and gargle.
All come from the Latin gula, meaning “throat”. You do gargle with your throat… and a gargoyle — although we associate it with the demon statues in churches — is, literally, a water spout. Yes, water used to spout out of the mouths of the gargoyles!
