Morphology
The meaning is directly built from 'aneroid' (without liquid) + 'barometer' (a device measuring air pressure), so a learner who knows both constituents can infer it refers to a barometer that operates without liquid. This technical compound follows transparent compositional naming and has equivalents in other languages, supporting immediate inferability.
Etymology
Aneroid barometer has the word aneroid, meaning 'without liquid', and the word barometer, a tool for measuring air pressure. Inside it a small, flexible metal box bends as the air pushes on it, so the instrument measures air pressure 'without liquid'.
