Forms

nōtiō f (genitive nōtiōnis); third declension[1]

Etymology

It is from nōscō “to get to know”, through its participle nōtus, with the suffix -tiō.[2][1][3]

Earliest recorded meaning

The OLD's earliest citation is from Plautus, quid tibi hanc nōtiōst? “what business have you with her?”.[2][4][5] Köbler dates Plautus c. 250–184 BC.[6]

Semantic evolution

In Plautus it meant acquaintance with a person.[2][4] In Cicero it meant a judicial inquiry, as of the censors, and a concept, idea.[2] Etymonline says Cicero used it to translate the Greek ennoia.[3]

In Ecclesiastical Latin it meant a notion, idea, conception, or examination.[7] British Medieval Latin used it for knowledge, understanding.[8] It was borrowed into French notion, Italian nozione and Spanish noción, and gave English notion in the late 14th century.[1][3]
