Mariotte's + law
The possessive construction 'Mariotte's law' signals a named scientific law, so a learner who knows 'law' will infer it denotes a scientific/general rule and that it is named after a person. However, the proper name 'Mariotte' carries no lexical clue to the specific relation (pressure ∝ 1/volume), so the precise meaning cannot be derived from the parts.
Etymology
Mariotte's law is named after a scientist who showed a simple idea: when you make a gas's space smaller, the 'pressure' goes up. Think of pushing a syringe or squeezing a balloon—the air has less room and pushes harder, so the law explains the link between 'pressure' and 'volume'.
