(Wikipedia excerpt:  “…A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. Also, leverage is mechanical advantage gained in a system. It is one of the six simple machines identified by Renaissance scientists.

A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever. As such, the lever is a mechanical advantage device, trading off force against movement. The word “lever” entered English around 1300 from Old French, in which the word was levier.

This sprang from the stem of the verb lever, meaning “to raise”. The verb, in turn, goes back to the Latin levare,[1] itself from the adjective levis, meaning “light” (as in “not heavy”). The word’s primary origin is the Proto-Indo-European stem legwh-, meaning “light”, “easy” or “nimble”, among other things. The PIE stem also gave rise to the English word “light”.[…”)
