Pronunciation

  • Classical: [ˈtɛr.ɡʊs][1]
  • Ecclesiastical: [ˈtɛr.ɡus][1]

Forms

tergus n (genitive tergoris); third declension[1] Plautus has the older form tegus.[2][3]

Etymology

It is from Latin tergum (“back”), with a third-declension ending modelled on pectus (“breast”);[4] de Vaan lists it among the derivatives of that noun.[5] Wiktionary allows a blend with ⟨tegus, tegoris⟩, which may have had its own origin.[1][4] The origin of the base is unclear: Walde–Hofmann and Pokorny derived it from a root Proto-Indo-European *(s)ter- (“to be stiff”) with a suffix ⟨-g-⟩, assuming that it first meant the stiff hair on an animal's back, but de Vaan finds no evidence for this.[5]

Earliest recorded meaning

De Vaan dates it from Ennius,[5] who uses it of a back covered by a thick cloak.[4] Plautus, who also has the form tegus, writes of meat racks laden with backs of meat.[3][2]

Semantic evolution

Mostly poetic and post-Augustan, it is the back of an animal, especially as meat, and the body of an animal;[4][3][6] Virgil and Ovid also use it of a person's back.[4] From the back it passes to the hide: in Virgil hides are torn from the ribs,[4][7] Pliny the Elder writes of the elephant's hide, very hard on the back, Ovid of the hides of a shield and Martial of a cuirass.[4][2][7] Celsus uses it of the coat of an organ and of the foreskin, and Mela of a narrow ridge of land.[4] Alcuin's work on spelling notes that terga is used of people and tergus, plural tergora, “hides”, of four-footed animals.[8]

Usage notes

Gaffiot records a rare second-declension tergus, -ī (masculine), used like tergum in Plautus.[2] Döderlein distinguishes tergus, the coarse skin of an animal covering the edible flesh, from cutis, the finer skin of people, while pellis and vellus are skins together with their hair.[10]
