Greek and Latin Roots of English: Barometer


According to the Cambridge Dictionary barometer is " a piece of equipment that measures air pressure (the force of the air) and shows when the weather will change", for example, you can see a barometer in the pic.


According to the Etymology Dictionary barometer derives from the Greek baros, meaning "weight", + -meter measure. Probably coined (and certainly popularized) by English scientist Robert Boyle (1627-1691).


Baritone, from barytonos (deep-toned, deep-sounding) has got the same root as barometer, but at the same time as isobar or barycenterOther words with the root -meter thermometer, speedometer or anemometer.
