Pronunciation
Definition
Meaning and Definition
Operating without fluid; specifically, a barometer that measures atmospheric pressure using a flexible metal box instead of liquid.
A general term for devices operating without liquid, originally describing a type of barometer. It can conceptually extend to any mechanism relying on mechanical rather than hydraulic or pneumatic fluid-based operation.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage; it is a precise technical term used identically in both varieties.
Connotations
Neutral technical term. May carry a slight 'historical' or 'traditional' connotation, as modern electronic sensors have largely superseded aneroid barometers.
Frequency
Equally low frequency in both dialects, confined to meteorology, aviation, antique collecting, and some engineering contexts.

FAQ
Frequently Asked Questions
Primarily yes, in the term 'aneroid barometer'. The principle is also used in aneroid altimeters and sphygmomanometers (blood pressure cuffs), but 'aneroid' alone almost always refers to the barometer.
It comes from French 'anéroïde', coined in the 19th century from Greek 'a-' (without) + 'nēros' (wet, liquid) + '-oid' (resembling). It literally means 'resembling something without liquid'.
It is less accurate than a well-made mercury barometer and requires periodic calibration. However, its portability and lack of hazardous liquid made it popular for field use and in homes before digital instruments.
It is highly unlikely you would need to, unless you are specifically discussing antique instruments, basic meteorology, or aviation. Most people would simply say 'barometer'.
Operating without fluid.
Aneroid is usually technical in register.
Aneroid: in British English it is pronounced /ˈæn.ə.rɔɪd/, and in American English it is pronounced /ˈæn.ə.rɔɪd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'A NEedle Reads Over InDial' – an aneroid barometer uses a needle to read pressure over a dial, with no liquid.
Conceptual Metaphor
DRYNESS FOR MECHANICAL OPERATION (contrasted with wet/fluid-based instruments).
