Morphology

Henry + Cavendish

Both constituents are personal names with no lexical meaning a learner can compose; knowing 'Henry' and 'Cavendish' does not let a B1 learner infer that this refers to an 18th‑century British chemist and physicist. This is a referential proper name requiring world‑knowledge, so its meaning is not derivable from the parts.

Etymology

Henry Cavendish was a quiet British scientist who discovered a light gas we now call hydrogen and who made a careful experiment to 'weigh' the Earth and find its density. That's why his name is remembered for showing that water contains hydrogen and for measuring the Earth's density.
