Etymology

It is inherited from Middle English professen,[2][3] which the dictionaries explain in several ways.[4][5][6] The revised OED takes it as borrowed from Anglo-Norman professer, recorded as a past participle, "admitted into a religious order", in the late 13th or early 14th century, and its source borrowed from Latin profiteor (“to state openly, declare, avow”).[4] The Merriam-Webster Unabridged, Klein, Skeat and the Shorter Oxford start from the participle professed, which goes back to Old French profes (“that has taken a religious vow”), from Latin professus, with the later senses coming straight from Latin;[5][7][8][9] the Middle English Dictionary, the American Heritage Dictionary and Etymonline also name Medieval Latin professō.[2][3][6] Etymonline and Barnhart also allow for a back-formation from profession.[6][10] The Latin verb is formed from prō- (“forth, in public”) and fateor (“to acknowledge, confess”),[4][11][6] which also gave confess and is related to fable, fame and fate.[11] Etymonline connects it with for (“to speak”) and Proto-Indo-European *bha- (“to speak, tell, say”).[6] Compare Spanish profesar, Italian professare and French professer, the French verb being recorded only from 1584.[4]

Earliest recorded meaning

To be professed, to have taken the vows of a religious order: William of Shoreham's poems, written before 1333 and in a manuscript of about 1350,[4][10] while Etymonline says early 14th century.[6] The Anglo-Norman verb had the same use in the early 14th century, alongside to declare one's faith and to dedicate oneself.[12] Two older words from the Latin participle died out: a noun profess, the declaration made on entering a religious order, from about 1325 to 1450, and an adjective profess, professed, from 1340 to 1896.[4]

Semantic evolution

Weekley says that before 1500 the word had only its religious sense,[13] and the Latin verb had already taken up the taking of vows, in Augustine.[4] The admission of a person into an order is recorded from about 1430.[4] Barnhart treats the sense of declaring openly, recorded from 1526, as a direct borrowing of the Latin sense,[10][6] and finds to lay claim to in Palsgrave's dictionary of 1530,[10][4] a sense that has often implied insincerity.[4][14] To declare one's faith in a religion or principle followed in 1549.[4][9] A separate line comes from the Latin verb's sense "to teach": to teach a subject as a professor is recorded from about 1532,[4] and Johnson (1755) still defined the verb as to declare in public one's skill in an art or science so as to invite work.[15] Ayto explains professor as someone who publicly claims knowledge of a field and profession as the activity in which someone claims a skill.[11] Shakespeare's Julius Caesar has it for making protestations of friendship, a use last recorded in 1849.[4][9]
