Pronunciation

  • Classical: [ˈtɔr.pɪ.dʊs][1]
  • Ecclesiastical: [ˈtɔr.pi.dus][1]

Forms

torpidus (feminine torpida, neuter torpidum); first/second-declension adjective[1]

Etymology

It is from Latin torpeō (“to be numb, stiff”) + -idus.[2][1] The verb goes back to Proto-Italic *torp-ē- (“to be stiff”) and Proto-Indo-European *trp-eh₁- (“to be stiff”).[3] Cognate with Lithuanian tir̃pti (“to coagulate, grow stiff”).[3]

Earliest recorded meaning

It is first found in Livy (59 BC–17 AD), meaning numb or paralysed: men heavy with sleep and then struck with fear.[2][4]

Semantic evolution

Livy also uses it of men stunned by amazement, and Apuleius of people numb with dread.[2] Later it was used of a fish's numbed tail by Ausonius, and by Lactantius.[5] A medieval glossary derives it from torpeō and gloss it with piger and segnis, “sluggish”.[6]

English torpid (1610s) comes from it, at first meaning “benumbed”; the sense “sluggish, apathetic” followed in the 1650s.[7]

Timeline

  • 59 BC–17 AD – Livy uses it of men numbed by sleep and fear.[2][4]
  • c. 125–175 AD – Apuleius uses it of people numb with dread.[2][4]
  • 1610s – English borrows it as torpid.[7]
