Derivation
First attested

Ultimate origin
Proto-Indo-European (*pótis)

Pronunciation

  • Classical: [ˈɪm.pɔ.tẽːs][1]
  • Ecclesiastical: [ˈim.po.tens][1]

Forms

impotēns (genitive impotentis, superlative impotentissimus, adverb impotenter); third-declension one-termination adjective[1] It is also spelled inpotēns.[2][3]

Etymology

It is formed from the negative in- (“not”) and potēns (“powerful”).[2][4][1] De Vaan derives ⟨potēns⟩ from a stative verb Proto-Italic *potē- (“to be master”), from the noun *poti- (“master”), Proto-Indo-European *pótis (“master, lord”), cognate with Sanskrit पति (páti-, “lord, master”), Ancient Greek πόσις (pósis, “husband”) and Lithuanian pàts (“husband”).[5]

Earliest recorded meaning

Its first example in the OLD is Terence's Andria, of a man “so headstrong” as to want to keep her against the citizens' custom;[2][6] Köbler gives Cicero.[2][6]

Semantic evolution

It is powerless or weak, as Cicero's laws that serve “the help of the powerless”.[2][3] With a genitive it is having no control over something, as Livy's Gauls blazing with anger, “which that race cannot control”, and impotēns suī is beside oneself.[2]

Absolutely it is lacking self-control, headstrong, violent or intemperate, of persons, of feelings and acts, as Cicero's “so unbridled and cruel inhumanity”, and in poetry of the wild sea, as Catullus' “so many raging straits”.[2][3] In medieval Latin it is helpless, unable to defend oneself.[7] English impotent came from it through Old French in the late 14th century.[8]
