Pronunciation

  • Classical: [pɛrˈtɛ.nu.ɪs][1]
  • Ecclesiastical: [perˈtɛː.nu.is][1]

Forms

pertenuis (neuter pertenue); third-declension two-termination adjective[1]

Etymology

It is from Latin per- + tenuis (“thin”).[2][3][1] De Vaan traces that adjective to Proto-Italic *tn̥(a)u- and Proto-Indo-European *tnh₂-(e)u- (“thin”).[4]

Earliest recorded meaning

Köbler dates it from Cicero,[5] who uses it six times, mostly figuratively; the TLL notes that it is rare elsewhere.[3] In On the Orator he says that the art of speaking seems to him either non-existent or very slight.[2][3]

Semantic evolution

Cicero uses it of a very slight suspicion, a very slender hope of safety and a flimsy piece of evidence.[2][6] In the literal sense of something very thin or fine, Pliny the Elder quotes it from Cato of very fine sand, words not found in Cato's book on farming.[3][6] Later authors use it of small feet, a meagre inheritance and a scanty daily living.[3]

Timeline

  • 81–43 BC – Cicero uses it of a slight art, suspicion and hope.[2][5]
  • 23/24–79 AD – Pliny the Elder quotes it from Cato of fine sand.[3][5]
