Sense: noun/1

All four words refer to long, rigid objects, but each has a different focus. A 'bar' is the most general term — any long piece of metal or wood, not necessarily used for lifting. A 'handle' is specifically the part you grip to operate something, and it may not provide mechanical advantage. A 'crowbar' is a curved metal tool with a split end, designed for prying nails and forcing things open; it is a specific type of lever. A 'pry bar' is similar to a crowbar but usually straighter and smaller. A 'lever' is the broadest mechanical concept: any rigid bar that pivots on a fulcrum to multiply force. For example, you use a crowbar to pry open a crate, but a simple plank used to roll a boulder is still a lever even though it has no special shape.

Etymology

LatinOld FrenchEnglish

The word 'lever' comes from Old French 'levier' meaning 'a lifter', which developed from the Latin verb 'levare' meaning 'to raise or lift up'. This Latin verb itself comes from 'levis' meaning 'light in weight' — the idea being that a lever makes a heavy object feel light by multiplying the force you apply. The figurative sense of using something as a tool of influence developed in the mid-19th century.
