Forms
īnsipiēns (genitive īnsipientis, adverb īnsipienter); third-declension one-termination adjective[1] Catullus has the spelling insapiens, which Cicero rejects.[2]
Etymology
It is from Latin in- (“not”) + sapiēns (“wise”), with ⟨a⟩ weakened to ⟨i⟩ in the second syllable.[2][1] sapiēns is the present participle of sapiō (“to taste; to be wise”), which de Vaan traces to Proto-Italic *sap-i- and Proto-Indo-European *sh1p-i- (“to notice”), though the internal laryngeal is uncertain and the root may have to be left as ⟨*sHp-⟩.[3] Cognate with Oscan sipus (“knowing”) and Old Saxon ansebbian (“to remark, notice”).[3]
Earliest recorded meaning
De Vaan records it from Plautus,[3] who has a character say sed ego insipiens nova nunc facio, “but I, fool that I am, am now doing something new”.[4]
Semantic evolution
It means unwise, foolish, and is also used as a noun, a fool.[2][1] Plautus already has the comparative, quis homost me insipientior, “what man is more foolish than I?”[4] Cicero speaks of a lucky fool, insipiens fortunatus, and sets the talk of the unwise against that of the wise man;[4] Seneca has the superlative.[4] The adverb insipienter, foolishly, is found from Plautus and Cicero.[4] In Church Latin it is foolish, unwise.[5]
