Forms

īnscientia f (genitive īnscientiae); first declension[1]

Etymology

It is from Latin īnsciēns (“not knowing”) + -ia,[2][3] like scientia beside sciēns.[3] īnsciēns is formed from in- (“not”) and sciō (“to know”),[1] which de Vaan traces to Proto-Italic *skije/o- (“to know”) and Proto-Indo-European *skh₁-i(e/o)- (“to incise”), assuming that “to know” developed from “to distinguish, decide”.[4] Cognate with Ancient Greek σχάω (skháō, “to slit open”).[4]

Earliest recorded meaning

Köbler dates it from Cicero,[5] who in the Pro Sulla speaks of such great darkness of error and ignorance, in tantis tenebris erroris et inscientiae.[6]

Semantic evolution

It is lack of knowledge, ignorance, inexperience;[2][6] Lewis & Short compare īnscītia.[6] Caesar uses it with a genitive for the ignorance of the common people and of the enemy.[6] The rhetorician Grillius, commenting on Cicero's De inventione, defines it as saying that one does not know what one truly does not know.[3] It has no plural.[3]
