practitioner

Etymology

It is formed from English practitian + -er, practitian being an obsolete variant of practician,^[2][3][4][5] with a redundant ending on the model of parishioner.^[4][6] The OED derives it from practician or its source, Middle French practicien, with the suffix -er, and compares logicianer, musicianer and physicianer.^[7] Practician itself, recorded from about 1500, is borrowed from Middle French praticien, also practicien,^[7][4][8] formed from pratique (“practice”) and -ien;^[7][8] Etymonline traces it further to Late Latin practicus (“fit for action”).^[4] An earlier English word for the same person was practisour, from the late 14th century.^[4]

Earliest recorded meaning

A person engaged in the practice of medicine, such as a physician or surgeon: about 1543, in Thomas Phaer's translation of Goeurot's Regiment of Lyfe.^[7] Etymonline gives the first sense as one who learns from actual practice, from the 1540s.^[4]

Semantic evolution

Medicine came first, but by about 1555 the word was used of anyone practising a skill, art or discipline;^[7][4] from 1576 it was used specifically of a lawyer.^[7] From 1548 it also meant someone who habitually follows a course of behaviour, especially the rites of a religion;^[7][8] Johnson (1755) gave this as his third sense.^[9] In the same period, following the sense of practice "scheming", a practitioner could be a plotter or deceiver (1560–1872),^[7] which Johnson defined as one who uses "sly or dangerous arts".^[9][4] The phrase general practitioner originally meant someone who practised both medicine and surgery.^[4] From 1883 Christian Science used the word for an accredited healer.^[7][8][10]
