Etymology

Origin of clinician

First recorded in 1870–75; clinic + -ian

Explanation

A clinician is a doctor, nurse practitioner, or other health care worker who treats patients directly. When you go to the doctor with a sore throat, a clinician will ask you to stick out your tongue and say "Ahh." The word clinician is often used simply to mean "doctor," but it applies to any health professional who works one-on-one with patients, diagnosing or treating illness. A clinician might be a physician or nurse, a psychologist, or a speech-language pathologist. Doctors whose work keeps them in laboratories or research facilities, rather than working with patients, are not considered clinicians. The Greek root is klinike techne, "practice at the sickbed."
