Forms

imprūdentia f (genitive imprūdentiae); first declension[1] The spelling inprūdentia is also found.[2][3]

Etymology

It is from Latin imprūdēns (“unaware, unwise”) + -ia.[2][1][4] The adjective is in- (“not”) and prūdēns (“foreseeing, wise”), which de Vaan explains as a contraction of prōvidēns (“foreseeing”), from videō (“to see”); he traces videō to Proto-Italic *wid-ē- and Proto-Indo-European *uid-eh₁- (“to see”).[5]

Earliest recorded meaning

Köbler and the TLL date it from Terence,[6][4] who says in a prologue that if something is a fault, it is the poet's inadvertence.[2]

Semantic evolution

It means lack of knowledge or awareness, ignorance, as in Cicero; absence of intention, with per imprudentiam “by accident”; and lack of judgement or foresight, as Caesar blames a mishap on the imprudence of the Bituriges.[2][3] The TLL notes that the poets do not use it apart from Terence.[4] English took imprudence from French or directly from Latin in the early 15th century.[7]

  • 81–43 BC – Cicero of ignorance.[2][6]
