Morphology

compound + lever

The noun is transparently built from 'compound' (made of several parts) modifying 'lever' (a bar pivoting about a fulcrum), so a learner who knows both words can infer it refers to a lever made of or combining multiple levers/parts. This compositional pattern is literal and common across languages and technical registers, so the meaning is predictable for a B1 learner familiar with the constituents.

Etymology

Compound lever comes from the words compound, meaning 'made of parts', and lever, a simple bar that turns on a point. When two or more levers are joined, a small push can become a much larger force, like in scissors, so the term means 'a machine made of two or more levers that increases force'.
