Pronunciation

  • Classical: [ɪmˈpuː.beːs][1]
  • Ecclesiastical: [imˈpuː.bes][1]

Forms

impūbēs (genitive impūberis or impūbis); third-declension one-termination adjective (non-i-stem)[1]

Etymology

It is from Latin in- (“not”) + pūbēs (“adult; manhood”), “not yet adult”.[2][1] De Vaan, however, takes pūbēs to be an old s-stem; since s-stem adjectives with this ablaut were compounds in Proto-Indo-European, he assumes that ⟨impūbēs⟩ was the older word and that ⟨pūbēs⟩ was made from it by back-formation.[3] The further origin of the base is uncertain: Adams connects it with Sanskrit पुमांस् (púmāṃs-, “male, man”).[3]

Besides the inflection ⟨impūberis⟩ the word has a second one, ⟨impūbis⟩.[2][4]

Earliest recorded meaning

De Vaan's first author is Lucretius,[3] who uses it as a noun for a boy below the age of puberty.[2] Köbler lists it as early as the Twelve Tables.[5]

Semantic evolution

The word described a person who had not yet reached puberty or manhood, and as a noun such a person,[2] which was also a legal status: a statute forbids an impūbēs to give evidence, and the jurists use the word of minors as a class.[2] Poets used it for the beardless cheeks or body of a youth, and Ovid has annī impūbēs for the years of childhood.[2]

L&S notes that the form ⟨impūbis⟩ is the more frequent one but is not used by Cicero or Caesar.[4] In Ecclesiastical Latin it kept the senses “youthful, beardless, under age”,[6] and Wiktionary also gives it the sense “chaste”.[1]

Timeline
