Pronunciation
Forms
professor m (plural professores, feminine professora, feminine plural professoras)[1] 15th-century texts have the plurals professorees and profesores.[2] Dialect speech in Portugal has prefessor and pressor.[3]
Etymology
It is borrowed from Latin professor (“one who professes an art; a teacher”), a learned word first recorded in the 15th century.[2][4][5][1] The Latin noun is formed on professus, the past participle of profiteor (“to declare publicly; to profess; to teach”).[2][6][1] Nascentes explains it as “one who declares his knowledge before others”.[5] In Latin it is found after the Augustan age, of public teachers of rhetoric, grammar and the arts.[7]
Cunha lists the word under the verb professar, which has the same Latin root.[4] The same word is Galician profesor.[8]
Earliest recorded meaning
Houaiss's first sense is “one who professes a creed or a religion”.[2] A Galician document of 1454 calls a priest professor e prior, in the religious sense.[9][2]
Semantic evolution
Pereira's Thesouro (1697) has professor, ou professora, with Latin profitens.[10] Bluteau defines the professor as one who teaches an art or science in public, such as rhetoric or philosophy.[11] Morais (1789) still gives first the member of an order of knighthood who has made his profession, and then the teacher of an art or science.[12]
The word now means any teacher, from a primary school to a university, and figuratively an expert.[2][13] In Portugal it is also a title of university teachers with a doctorate.[14] The word passed into Kabuverdianu as profesor.[1]
