clinician

Etymology

It is borrowed from French clinicien,^{[2][3][4][5][6]} formed from clinique (“clinic”) and -ien (“-ian”),^[5][6][4] or, as the OED and Etymonline describe it, from Latin clīnicus on the model of the word for physician.^[2][3] The Latin word is from Ancient Greek κλινικός (klīnikós, “of the bed”), from κλίνη (klī́nē, “bed, couch”),^[3][1] from a suffixed form of Proto-Indo-European *klei- (“to lean”).^[3] Dictionary.com analyses it as clinic with the suffix -ian.^[7]

Earliest recorded meaning

A clinical observer or investigator: 1874, in H. C. Wood's Treatise on Therapeutics.^[2] Merriam-Webster Unabridged gives 1875 and Dictionary.com 1870–75,^[5][7] while Etymonline dates it to 1844, with the sense of one who makes a practical study of disease or of sick people.^[3]

Semantic evolution

It came to mean especially a doctor who deals directly with patients and is responsible for them, as distinct from one who works in a laboratory or on research.^[2][8][5] From 1897 it also meant a doctor who runs or works in a clinic, a sense of clinic that came from German in 1884.^[2][3] Merriam-Webster Unabridged extends it to anyone qualified in the clinical practice of medicine, psychiatry or psychology.^[5] English also formed its own clinicist, recorded from 1860.^[3]
