Etymology and origin of the Latin word extrinsecus
Forms
extrīnsecus (not comparable)[1]
Etymology
It is formed from exter (“outward”), in an adverbial form like ⟨extrim⟩, and secus (“beside, on the side”).[1][2][3] De Vaan lists it with ⟨secus⟩, like altrinsecus (“on the other side”), and traces ⟨secus⟩ to Proto-Italic *sekʷos (“separate”), following Klingenschmitt's Proto-Indo-European *se-ḱuo- (“by itself, separate”); cognate with Old Irish sech (“past, without”) and Welsh heb (“without”).[4] Priscian and Servius already discussed it among the local adverbs formed from prepositions.[5]
Earliest recorded meaning
Köbler's first source is Cato,[3] who tells the farmer to smear the bottom of a chest with oil lees, and the outside, feet and corners.[6]
Semantic evolution
It means “from without”, as Varro's hawk swooping in from outside, “on the outside, externally” (Cato), and in Celsus “outwards”.[6] Cicero uses it of things sought from an outside source, and of the gifts of fortune that come from outside, as birth and beauty.[6][2] In Late Latin it is also an adjective, “outer”, as in Tertullian.[2]
Church Latin glosses the adverb “on the outside, from without” and the adjective “outer, extrinsic, inessential”.[7] In medieval sources the adjective or noun can mean an exile.[8]
