Inclinometer

Part of speech: noun

Definitions

1. A device utilized for measuring the angle of slope with respect to the horizontal plane, often applied in geological or engineering tasks
2. An instrument that determines angular deviation from a vertical or horizontal position, particularly useful in various construction or excavation applications
3. A tool designed to gauge the angle of inclination or declination relative to a flat surface, commonly used in fields like architecture or geology

Etymology: The inclinometer is a plain technical coinage, built in English from parts that were already in the language for centuries. Its core is "incline," which came into English through Old French "encliner" from Latin "inclīnāre," meaning "to bend or lean toward." The "-o-" is a linking vowel, and "-meter" comes from French "-mètre," which in turn traces back to the Greek "métron," meaning "measure." Put together, the name literally means "a measure of leaning" or "a measure of slope." The Latin root "clīnāre" (to lean) is also the source of "recline" and "declination," so the instrument shares its core with words for bending, leaning and reclining. The "-meter" element is the same one found in "thermometer" and "barometer," which likewise pair a physical quantity with the Greek suffix for measurement.
