Pronunciation

  • UK: /pɹəˈfɪʃ.ənt/[1]
  • US: /pɹoʊˈfɪʃ.ənt/, /pɹəˈfɪʃ.ənt/[1]

Etymology

It is borrowed from Latin prōficiēns (“advancing, making progress; useful”),[2][3][4][5][6] the present participle of prōficiō (“to go forward, make progress; to be useful”),[2][3][4][7] formed from prō- (“forward”) and the combining form of faciō (“to make, do”),[4][7][8] from Proto-Indo-European *dʰeh₁- (“to set, put”).[7] Post-classical Latin used the participle as a noun for a person who has made progress, from the 4th century.[2] Etymonline and Barnhart also consider a back-formation from proficiency or a borrowing through Old French proficient;[7][9] the OED compares proficient (c. 1334), proficiente and proficiente.[2] It is related to profit.[10][11]

Earliest recorded meaning

The noun, a person with advanced skill or knowledge, an expert: 1589, in Nashe's Anatomie of Absurditie.[2][4] The adjective, skilled or expert, follows before 1593 in Marlowe's Doctor Faustus.[2][9][4]

Semantic evolution

The Latin idea of making progress was present in early English use: from 1598 to 1743 a proficient was also a learner who was making progress, first recorded in Shakespeare's Henry IV, Part 1, where the speaker is "so good a proficient" that he can drink with any tinker in his own language.[2][12] From 1614 to 1658 the adjective could mean "improving, advancing".[2][5] Johnson (1755) defined the noun as one who has made advances in a study.[12] The related proficiency meant "advancement, progress" from the 1540s, in Etymonline's dating,[7] but the OED dates it from 1597 in the sense of skill.[2] Only the sense "skilled, expert" survives, and the noun is now archaic.[13][5]
