Pronunciation

  • IPA (5th-century BC Attic): /lɛ̌ː.tʰaːr.ɡos/[1]
  • IPA (4th-century AD Koine): /ˈli.θar.ɣos/[1]
  • IPA (10th-century Byzantine): /ˈli.θar.ɣos/[1]

Forms

λήθᾱργος (lḗthārgos) m or f (neuter λήθᾱργον); second declension[1]

Etymology

Beekes considers it Pre-Greek, from Pre-Greek, because of its variation with λαίθαργος (laíthargos, “treacherous”): the alternation ⟨η⟩ / ⟨αι⟩ is typical of substrate words.[2][3] The PHILOGLOSSA database rates this as highly reliable.[4]

The traditional analysis is a compound of λήθη (lḗthē, “forgetfulness”) and ἀργός (argós, “idle”), “idle through forgetfulness”, which Frisk found hard to square with the illness.[5][1] Beekes thinks the word, or at least its meaning, was influenced by these words.[5][1][2] It was probably first an adjective with νόσος (nósos, “disease”) or πυρετός (puretós, “fever”) understood.[2][5]

Earliest recorded meaning

The Hippocratic writings use it for a lethargic fever, a disease of drowsiness.[2][4]

Semantic evolution

Aristotle and the Stoic Chrysippus use it for lethargy, and Galen and Paul of Aegina for the illness.[2][4] From Menander on it is also an adjective, “forgetful”.[2][1] Hesychius records other senses: “treacherous”, a dog that fawns but bites in secret (from Sophocles), and dull, sluggish horses.[6]

Latin borrowed it as lēthargus.[1] Modern Greek λήθαργος (líthargos) is a learned word for pathological deep sleep, figurative torpor, and in botany the dormancy of seeds.[7]
