Pronunciation

  • 5th-century BC Attic: /zdɛː.ló.ɔː/[1]
  • 4th-century AD Koine: /ziˈlo.o/[1]
  • 10th-century Byzantine: /ziˈlo.o/[1]

Forms

ζηλόω (zēlóō) [1] Doric ζαλόω (zalóō) (Theocritus).[2]

Etymology

It is a denominative verb formed from Ancient Greek ζῆλος (zêlos, “zeal, emulation, jealousy”) + -όω (-óō).[1][3] Beekes connects ζῆλος (zêlos) with ζητέω (zētéō, “to seek”) and δίζημαι (dízēmai, “to seek out”), and tentatively with Proto-Indo-European *ieh₂- (“to pursue, avenge”).[3] Babiniotis also thinks a link with the stems of these verbs and of ζημία (zēmía) probable.[4]

Earliest recorded meaning

Hesiod uses it of the rivalry of neighbours: “neighbour vies with neighbour” in the race to wealth.[5][3][2]

Semantic evolution

In Hesiod and the Homeric Hymn to Demeter it means to envy or be jealous of a person.[5][2] Tragedy and Attic prose added a positive sense, to count someone happy or enviable: “I envy you for dying before you saw the depths of misery”, says Aeschylus's chorus.[5][2] Thucydides and Plato use it for emulating a person or striving after a thing, and Euripides, Demosthenes and Menander for setting one's heart on honours or fame.[5][2]

The Septuagint uses it both for jealousy (also a husband's jealousy for his wife) and for zeal for something.[6][5] In the New Testament Paul urges his readers to “strive for the greater gifts”, and the Book of Acts says that the patriarchs sold Joseph out of jealousy.[7][5]

Modern Greek keeps ζηλώ (ziló) only as a learned, often ironic verb, to covet what others had before; the everyday verb is ζηλεύω (zilévo), from the Hellenistic ζηλεύω (zēleúō).[8][4][3]
