Gargoyle n: A roof spout in the form of a grotesque or fantastic creature projecting from a gutter to carry rainwater clear of the wall.

The word "Gargoyle" shares a common root with the word "Gargle"; which comes from "gargouille", a French word for "Throat". A true gargoyle is a waterspout. The word “gargoyle” is also a derivative from the Latin word, “gurgulio”, which had a double meaning, “throat”, and the “gurgling” sound water makes as it passes through a gargoyle. A carved creature that does not serve the purpose of a drain pipe is frequently referred to as a "Grotesque". legend has it, that a fierce dragon named La Gargouille described as having a long, reptilian neck, a slender snout and membranous wings lived in a cave near the river Seine. The dragon caused much fear and destruction with its fiery breath, spouting water and the devouring of ships and men. Each year, the residents of Rouen would placate Gargouille with an offering of a victim, usually a criminal, though it was said the dragon preferred maidens. Around 600, the village was saved by St. Romanus, who promised to deal with the dragon if the townspeople agreed to be baptized and to build a church. Romanus subdued the dragon by making the sign of the cross and then led the now docile beast back to town on a leash made from his priest's robe. La Gargouille was then burned at the stake, it is said that his head and neck were so well tempered by the heat of his fiery breath, that they would not burn. These remnants were then mounted on the town wall and became the model for gargoyles for centuries to come.

In movies such as Ghostbusters, the gargoyle was portrayed as a statue that would come alive and turn into a horrific beast which would act as a kind of pet for a devil. As you can read from the above, this is far from the truth.
