Etymology: "Fulcra" is the plural of "fulcrum," which English borrowed directly from Latin, where it meant "bedpost" or "the foot of a couch." The Latin word came from "fulciō," meaning "prop up" or "support," so the original idea was a physical support beneath something heavy. The sense of a pivot for a lever grew out of that notion of a prop: the point on which a bar rests and turns is, in effect, the thing that holds the load up. The Latin plural was "fulcra," which English retained, so this form is the older-style plural alongside the regular "fulcrums." Both are in use today, with "fulcrums" more common in general writing.
