lever

Noun: A lever is a simple machine that consists of a long, rigid bar that is pivoted at a fixed point called the fulcrum. When a force is applied to one end of the lever, it moves the other end, which can be used to lift or move a heavy object.

Adjective: Levered is an adjective that describes something that is moved or operated by a lever. For example, a levered gate is a gate that is opened or closed by a lever.

Verb: To lever is to move or operate something with a lever. For example, to lever open a door is to use a lever to open the door.

The word "lever" comes from the Old French word "lever", which also means "to raise". It was first used in English in the 13th century.

The Old French word "lever" is thought to be derived from the Latin word "levis", which also means "light" or "easy". This is because a lever can be used to make a heavy object seem lighter, by using a small amount of force to move a large object.
