Did you know?

This word comes straight from Latin. In the Roman empire, a terminus was a boundary stone, and all boundary stones had a minor god associated with them, whose name was Terminus. Terminus was a kind of keeper of the peace, since wherever there was a terminus there could be no arguments about where your property ended and your neighbor's property began. So Terminus even had his own festival, the Terminalia, when images of the god were draped with flower garlands. Today the word shows up in all kinds of places, including in the name of numerous hotels worldwide built near a city's railway terminus.
