Pronunciation

  • Classical: [sae̯ˈtoː.sʊs][1]
  • Ecclesiastical: [seˈtɔː.s̬us][1]

Forms

saetōsus (feminine saetōsa, neuter saetōsum); first/second-declension adjective[1] It is also spelled sētōsus.[2][3]

Etymology

It is from Latin saeta (“bristle”) + -ōsus.[2][1][4][5] De Vaan traces saeta to Proto-Italic *saitā- and Proto-Indo-European *séh₂i-to- (“cord”) or *sh₂éi-to-; most handbooks derive it from the root “to bind”, a link Schrijver finds very doubtful, but de Vaan points to the many derivatives of that root meaning “strap” or “cord”, from which a meaning “hair” could easily arise.[6]

Earliest recorded meaning

Köbler finds it first in Virgil,[4] who in the Eclogues speaks of the head of a bristly boar (saetosi caput apri).[3][7]

Semantic evolution

Lewis & Short call it mostly poetic.[3] Horace uses it of the bristly limbs of the companions of Ulysses whom Circe turned into swine, and of a shaggy forehead;[3] Celsus of a hairy chest and Pliny the Elder of a bull's ears.[3][8] Propertius has saetosa verbera, whips of hairy hide.[3][9][7]

In British Medieval Latin Aldhelm uses it of the fleeces of wethers, and the Liber monstrorum of the shaggy heads and bodies of monsters; it was also said figuratively of bristling invective.[10] It survives in Italian setoso and French soyeux, and English borrowed it as setose.[1]
