professor m (genitive professōris, feminine profestrīx); third declension[1]
Etymology
It is from Latin profiteor (“to declare publicly, profess”) + -tor.[2][1][3]
Earliest recorded meaning
Valerius Maximus says the teachers of that study are called sophists.[2] The TLL finds it only in prose, and Köbler dates Valerius Maximus to the 1st century AD.[3][4] Celsus, of the same period, calls philosophers sapientiae professōrēs.[5]
Semantic evolution
It was a person who claims expertise in an art or science, a teacher, and Lewis & Short call it post-Augustan.[2][5] Quintilian and Suetonius use it of teachers of rhetoric and grammar.[5][6] An inscription uses it of a candidate for the aedileship.[2]
In medieval Latin it was a scribe of a town council, a monk who has taken vows and a university teacher.[7][4] British writers used it of one who professes something, such as evangelical poverty.[8] English professor is recorded in the late 14th century as one who teaches a branch of knowledge.[9]
