Pronunciation

  • Classical: [pɪsˈkoː.sʊs][1]
  • Ecclesiastical: [pisˈkɔː.s̬us][1]

Forms

piscōsus (feminine piscōsa, neuter piscōsum); first/second-declension adjective[1]

Etymology

It is from Latin piscis (“fish”) + -ōsus.[2][1][3] The noun goes back to Proto-Italic *piski- and Proto-Indo-European *pisk- (“fish”), cognate with Old Irish íasc, Old High German fisk and Old Norse fiskr; de Vaan finds the vowel of the Celtic word difficult to account for.[4]

Earliest recorded meaning

Köbler records it first in Virgil,[5] who speaks in the Aeneid of rocks teeming with fish, piscosos scopulos.[2][6]

Semantic evolution

Ovid uses it of a river and of shallows, Seneca of rivers, Martial of the Tagus and the deep, and Justin of the Ocean.[7][6] Nonius records it in the sense “like a fish”.[8][9] Medieval British writers used it of waters rich in fish and also of things having to do with fish or fishing.[10] It lives on in Italian pescoso and Spanish pescoso.[11][9]
