Forms

profesor m (plural profesores, feminine profesora, feminine plural profesoras)[1]

Etymology

It is borrowed from Latin professor (“one who professes an art or science; teacher”).[2][3][4][1] The Latin agent noun is formed on professus, the past participle of profiteor (“to declare publicly; to profess, to teach”), which is prō- with fateor (“to confess, acknowledge”).[2][5][6] Corominas treats it with profesar and profesión in his article on confesar, which comes from the same Latin verb family.[2]

In Latin the noun named a person who claimed expertise in an art or science, a teacher;[6][7] Lewis and Short call it post-Augustan.[6][7] The same learned word is Portuguese professor, Galician profesor, French professeur and Italian professore.[8][1][9]

Earliest recorded meaning

Corominas's first record is Alonso de Palencia, 1490.[2][3] The Old Spanish Textual Archive has a single occurrence, in a text it dates to 1385.[10] The early sense is “one who professes something”: in 1587 a Franciscan in Puebla is a profesor de tan estrecha pobreza “professor of such strict poverty”.[11]

Semantic evolution

Autoridades defines professor as one who practises or teaches publicly a faculty, art or doctrine, with quotations on the professors of medicine.[12] Terreros, in the 1780s, has the doctor or master who teaches the arts and sciences from a university chair, and also the person learned in a faculty.[13] In the Americas there are a profesor en el arte de pilotaje in Santo Domingo in 1724 and a professor for each class in Peru in 1788.[11]

The Academy added the feminine profesora in 1843, with three senses: one who practises a science or art, one who teaches it, and one who studies it.[14][15] The sense “student” was still listed in 1869 and was gone in 1884, when the definition became a person who practises or teaches a science or art.[16][17] Today the word names any teacher, especially in Spain, as well as a university professor, and also a musician in an orchestra.[1][18] It is often clipped to profe.[1] It was borrowed into Tagalog as propesor.[1]
