Earliest recorded meaning

The OLD's first citation is Terence, whose character needed no adviser.[2][4] Köbler dates Terence 190–159 BC.[5]

Semantic evolution

It meant one who reminds or advises, a counsellor, guide, as in Terence, Sallust and Seneca, and a legal adviser.[2][6] It also meant a prompter who reminds someone what to say, and a nomenclator who tells a candidate the names of voters, as in Cicero.[2]

In Ecclesiastical Latin it was an admonisher, adviser, overseer, prayer leader and superintendent.[7] In Medieval Latin it meant one who teaches, advises or warns.[8] English monitor was borrowed in the 1540s for a senior pupil keeping order.[3]
