Meaning: As a noun, a lever is a rigid object used with a fulcrum to multiply the mechanical force that can be applied to another object.
As a verb, to lever means to move or force something using a lever.
Word history: The word lever comes from the Old French word levier, meaning to raise.
This, in turn, derives from the Latin word levare, which means to lift or lighten. The concept of a lever has been known and used since ancient times, with the Greek mathematician Archimedes famously saying, Give me a place to stand, and I shall move the Earth with a lever.
