aneroidadj.n.

Brit.

/ˈanərɔɪd/, U.S.

/ˈænəˌrɔɪd/

Origin: A borrowing from French. Etymon: French anéroïde.

Etymology: < French anéroïde, adjective (1844 in baromètre anéroïde aneroid barometer, designating a barometer invented by Lucien Vidi (1805–66), French mechanic) < ancient Greek ἀν- an- prefix² + classical Latin āēr air n.¹ + French -oïde -oid suffix.The use as noun denoting the type of barometer is apparently first attested later in French (1860 or earlier).

A. adj.

a. Originally: designating a type of barometer in which air pressure is measured by the expansion and contraction of a flexible capsule that has been exhausted of air. In later use also: designating any of several instruments that employ similar means to measure the pressure of other fluids (esp. blood).
