Pronunciation

  • 5th-century BC Attic: /zdɛ̂ː.los/[1]
  • 4th-century AD Koine: /ˈzi.los/[1]
  • 10th-century Byzantine: /ˈzi.los/[1]

Forms

ζῆλος (zêlos) m (genitive ζήλου); second declension[1] Doric ζᾶλος; later also neuter τὸ ζῆλος, genitive ζήλους.[2][3][4]

Etymology

It is inherited from Proto-Indo-European *yéh₂los,[1] from the root *yeh₂- (“to pursue, search, ask”).[3][1] Beekes groups it with ζητέω (zētéō) “to seek”, δίζημαι (dízēmai) “to look for” and ζημία (zēmía) “penalty”, following García Ramón's explanation of Hesychius' gloss Ζητήρ (Zētḗr) as “avenger”, like a Vedic word for “avenger” from a root meaning “to ask, require”.[3][1]

Ancient writers derived it from ζέω (zéō) “to boil”: zeal, said Simplicius, is a burning desire, and the Etymologicum Gudianum adds a derivation from ζάλη (zálē) “squall”, because jealousy throws a storm into a person.[5]

Earliest recorded meaning

Hesiod is the first to use it: in the Works and Days (195) it is jealousy or Envy personified, and in the Theogony (384) Zelos, “Emulation”, is a son of Styx, brother of Victory, Power and Strength.[2][6][7]

Semantic evolution

Classical Greek used it both for envious jealousy, often coupled with φθόνος (phthónos) (Democritus, Lysias, Plato), and, more often, in a good sense, for emulation of what one admires (Plato, Aristotle).[2][6] Tragedy used it for enviable good fortune and for eager passion for someone or something.[6]

In the Septuagint it renders fervour, zeal and jealousy, and in the New Testament it is zeal, ardent dedication to something.[8][4] Late Latin borrowed it as Latin zelus, a Church word that gave English zeal.[9] Modern Greek ζήλος (zílos) is a learned revival.[10]

Timeline

  • Before the 6th century BC – Hesiod names Envy and the god Zelos.[2][6][11]
  • 5th century BC – Sophocles uses it for zeal for kinsmen.[2][4][11]
  • 5th century BC – Euripides uses it for the rivalry for a woman's hand.[2][11]
  • 4th century BC – Aristotle uses it for emulation.[2][6][11]
  • 1st century AD – The Second Letter to the Corinthians (9:2) uses it for zeal.[4]
  • Late 14th century – English borrows zeal from Old French and Late Latin.[9]

Meanings

Noun

  1. Jealousy, envy; personified, Envy.[6][2]

Word family

  • ζηλοτυπία (zēlotupíā)
  • ζηλότυπος (zēlótupos)
  • ζηλόω (zēlóō)
  • ζηλωτής (zēlōtḗs)
  • χαμαίζηλος (khamaízēlos)

Usage notes

Ammonius distinguishes it from φθόνος (phthónos): ζῆλος is the imitation of something one thinks good, out of desire for it, φθόνος a grudge at goods that others have and we lack;[12] ζηλοτυπία is the jealous passion itself.[12] The Atticist lexicon notes that it was used of jealousy, not only of emulation.[13]
