Forms
stultus (feminine stulta, neuter stultum, comparative stultior, superlative stultissimus, adverb stultē); first/second-declension adjective[1]
Etymology
It is inherited from Proto-Italic *stoltos,[1] and belongs with stolidus (“dull, stupid”).[2][3] De Vaan reconstructs ⟨*stl-to-⟩ and calls the further origin uncertain;[3] Pokorny derives both adjectives from Proto-Indo-European *stel- (“to place, stand”), so that they first meant “inert, standing still”.[3][4] Wiktionary compares Ancient Greek στελεός (steleós) and, with less certainty, Proto-Germanic *stultaz (“proud”).[1]
Earliest recorded meaning
Köbler dates it from Plautus.[4] Plautus has quid stulta plōrās?, “why are you crying, silly girl?”, and stultior stultō fuistī, “you were more of a fool than a fool”.[2]
Semantic evolution
Stultus is “slow-witted, stupid, foolish” of persons, and of actions and words “silly, inept”.[2][5][1] Plautus piles up its synonyms: stultī, stolidī, fatuī, fungī, bardī, blennī, bucconēs, “fools, dolts, idiots, mushrooms, blockheads, drivellers, babblers”.[5] Stultōrum fēriae, “the fools' feast”, was a name for the Quirinalia, when those who had missed their own festival sacrificed (Ovid, Festus).[2]
As a noun stultus is “a fool”;[6] Church Latin glosses it “silly, stupid”.[6]
