Pronunciation

  • UK: /pɹækˈtɪʃənə/[1]
  • US: /pɹækˈtɪʃənəɹ/[1]

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]
