Morphology
aneroid = an + eroid
Although the prefix 'an-' (not) is recognizable, the stem 'eroid' is not a standalone English word and the meaning 'without liquid' is not transparently deducible for an average B1 learner.
Etymology
Aneroid comes from Greek parts, with a- meaning 'not' and a part that meant 'water' or 'liquid', so the whole word literally means 'without liquid'. That's why an aneroid barometer measures air pressure without using any liquid.
