Pronunciation

  • Classical: [ˈtɛ.nu.oː][1]
  • Ecclesiastical: [ˈtɛː.nu.o][1]

Forms

tenuō (present infinitive tenuāre, perfect active tenuāvī, supine tenuātum); first conjugation[1]

Etymology

It is from Latin tenuis (“thin”) + -ō.[2][1][3] De Vaan traces tenuis to Proto-Italic *tn̥(a)u- and Proto-Indo-European *tnh₂-(e)u- (“thin”), remade from a u-stem into an i-stem, and compares Sanskrit तनु (tanú-, “thin, slender”) and Ancient Greek ταναός (tanaós, “thin, elongated”).[4]

Earliest recorded meaning

Its first quotation is from Lucilius, on spelling: one is to make the sound thin, with ⟨i⟩, in pilam and pilum, but add ⟨e⟩ for the plural peila.[2]

Semantic evolution

It is to make thin or slender: Ovid has a man's legs joined and tapering into a snake's tail, and the moon thinning its full orb.[2] It is to wear down, as Lucretius' ring worn thin on the finger and Ovid's ploughshare, and to make the body lean: Virgil's breeders thin their herds on purpose.[2][3] It is used of reducing a swelling, of streams shrinking into many channels, and of making things less dense: Horace has the night air thin out the dregs of Massic wine.[2] It is also to reduce non-material things, as anger, to make the voice thin, as in Ovid, and to belittle: in Horace one is told to stop diminishing great things in small measures.[2] Lewis & Short find it in poetry and post-Augustan prose.[3] Church Latin glosses it to lessen or make thin.[5] English attenuate comes from its compound attenuō.[6]
