語源 1

From Proto-Italic *dorsom, probably derived from deorsum (“downwards”) < *dēvorsum, with a semantic shift from "turned away from" > "back". Ramat notes that the two terms' contemporaneous use suggests that one was not a phonetic development of the other; however, De Vaan explains this as a case of lexical differentiation in the written and by extension spoken forms. A potential connection with a Proto-Celtic *dros-man, giving Old Irish druimm (“back, ridge”), is unclear.

   • 29 BCE – 19 BCE, Virgil, Aeneid 1.108–110:

     Trīs Notus abreptās in saxa latentia torquet —
     saxa vocant Italī mediīs quae in flūctibus ārās —
     dorsum immāne marī summō [...].

     Three [ships] were taken away [by] the Southwind, hurled into hidden rocks – rocks the Italians call the Altars, which [are] in the middle of the waves – a vast reef near the surface of the sea.
     (This “vast reef” or “huge ridge” posed a hidden danger; understood more imaginatively, a “monstrous spine” of rock destroyed the ships. Notus was the Greek south wind.)

   • 27 BCE – 25 BCE, Titus Livius, Ab Urbe Condita I.3:

     This [new city] was named Alba Longa, from its position, as it lay stretched out along the ridge
