physicist

Etymology

It is formed from English physic + -ist,^[2][3] or from physics and -ist in Etymonline, Klein and Dictionary.com;^[4][5][6] the OED takes its main sense after physics.^[2] Physic is from Old French fisike (“natural science, art of healing”) and directly from Latin physica (“study of nature”),^[4] from the feminine of Ancient Greek φυσικός (phusikós, “pertaining to nature”), from φύσις (phúsis, “nature”).^[5][4] In its modern sense the word was coined by the Reverend William Whewell, the English polymath, for a "cultivator of physics" as distinct from a physician;^[4][5] in “The Philosophy of the Inductive Sciences” (1840) he wrote, "As we cannot use physician for a cultivator of physics, I have called him a physicist", in the same passage that introduced scientist.^[4] In French both the medical and the scientific senses belong to French physicien, used of an expert in physics from 1680.^[2]

Earliest recorded meaning

An expert in medical science: 1716, a rare sense that soon died out.^[2][3][4]

Semantic evolution

Etymonline dates the modern sense to 1836, when Whewell coined it;^[4] the OED's first quotation for an expert in or student of physics is from 1837,^[2] and the first edition of the OED and Merriam-Webster date it to 1840 or about 1840.^[7][8][9] For a time the word was also used more widely of anyone who studies nature or natural science (1858, in a letter by Kingsley),^[2] and in the 1870s of a believer in physicism, the theory that living things have a purely physical origin, as opposed to a vitalist.^[2][3] The OED marks both senses obsolete,^[2] while Merriam-Webster still records them, the first as archaic.^[9]
