Pronunciation

  • IPA (Classical): [tɔrˈpeː.doː][1]
  • IPA (Ecclesiastical): [torˈpɛː.do][1]

Forms

torpēdō f (genitive torpēdinis); third declension[1]

Etymology

It is from Latin torpeō (“to be numb”) + -ēdō.[2][1] Etymonline traces torpeō to Proto-Indo-European *ster- (“stiff”).[3]

Earliest recorded meaning

Cato, quoted by Gellius, says that sluggishness does more harm than exercise.[2][4] Köbler dates Cato 234–149 BC.[5]

Semantic evolution

Its first sense was sluggishness, lethargy, numbness, rare and not in Cicero or Caesar: Sallust and Tacitus use it of inertia that seized the mind.[2][4][6] It was also the electric ray, a fish whose touch numbs, in Varro, Cicero and Pliny the Elder.[2][7] Isidore says it is named because it makes the body numb if anyone touches it alive.[8]

Medieval writers kept both senses, sloth and the fish.[9] English torpedo is recorded in the 1520s for the electric ray.[3]
