  • 10th-century Byzantine: /ˈθa.na.tos/[1]

Forms

Etymology

It is from Ancient Greek θνῄσκω (thnēískō, “to die”), formed from the verb's root (as in the aorist θανεῖν (thaneîn)) with the suffix found in βίοτος (bíotos, “life”), which goes back to Proto-Indo-European *-etos.[1][2][3] Beekes reconstructs this root, which also appears in θνητός (thnētós, “mortal”), as *dʰn̥h₂-.[4]

The further origin is debated.[4][5] An old comparison with a Sanskrit aorist meaning “he disappeared, went out” and a participle meaning “dark” led to a root *dʰwenh₂-; on this view the sense “die” began as a euphemism (“go out like a fire”), as Frisk and Chantraine explain.[4][5][6][7] Beekes finds the comparison uncertain; the LIV instead puts the Greek words under a root *dʰenh₂- (“to set off running, to make off”), with Vedic verbs meaning “to flow” (with a prefix, “to die”) and Tocharian A tsnāntär (“they flow”), which he thinks possible but not wholly convincing.[4]

Ancient grammarians offered fanciful derivations: Orion took it from τείνω (teínō, “to stretch”), because death stiffens the body, and Philoxenus built it from a verb meaning “to set aside”.[8]

Earliest recorded meaning

It is common from the Iliad and the Odyssey on, meaning death, natural or violent;[2][3] Homer has the phrase θάνατόνδε “to death” and personifies Death as a god.[2][3][9]

Semantic evolution

Homer and Hesiod already treat Death as a god, and tragedy and comedy keep the figure.[3][9] In Classical Greek the word covers the moment and manner of dying, the state of being dead, a killing, and in law the death penalty: a δίκη θανάτου was a capital trial.[3][2] Menander's phrase “to look deaths” meant to look deathly pale.[3]

In the Septuagint it also means a deadly pestilence, and in the New Testament death is seen not only as the end of physical life but as separation from God, set against eternal life; the phrase “to taste death” means to die.[10][11] Medieval vernacular Greek kept the word unchanged, and it is still Modern Greek θάνατος (thánatos).[12][13]

English Thanatos, Freud's “death instinct” (1935), is taken from it.[14]

Timeline

  • Homer – The Iliad and the Odyssey use it for death and personify Death.[2][3][9]
  • Before the 6th century BC – Hesiod's Theogony presents Death as a god.[9][3]
  • 5th century BC – Herodotus and Thucydides use it of the death penalty.[3][15]
  • 4th century BC – The orator Lycurgus calls the destruction of a city its death.[2][3][15]
  • 1st century AD – The New Testament opposes it to life, as spiritual death.[11]
  • 1935 – English borrows Thanatos as a term of Freudian psychology.[14]
