Sanskrit Dyaus/Dyaus Pita), Latin (compare Jupiter, from Iuppiter, deriving from the Proto-Indo-European vocative *), deriving from the root *dyeu- ("to shine", and in its many derivatives, "sky, heaven, god"). Albanian is also a cognate of Zeus. In both the Greek and Albanian forms the original cluster *di̯ underwent affrication to *dz. Zeus is the only deity in the Olympic pantheon whose name has such a transparent Indo-European etymology. The earliest attested forms of the name are the Mycenaean Greek , di-we and , di-wo, written in the Linear B syllabic script. Plato, in his Cratylus, gives a folk etymology of Zeus meaning "cause of life always to all things", because of puns between alternate titles of Zeus (Zen and Dia) with the Greek words for life and "because of". This etymology, along with Plato's entire method of deriving etymologies, is not supported by modern scholarship.

He swallows each child as soon as they are born, having received a prophecy from his parents, Gaia and Uranus, that one of his own children is destined to one day overthrow him as he overthrew his father. This causes Rhea "unceasing grief", and upon becoming pregnant with her sixth child, Zeus, she approaches her parents, Gaia and Uranus, seeking a plan to save her child and bring retribution to Cronus. Following her parents' instructions, she travels to Lyctus in Crete, where she gives birth to Zeus, handing the newborn child over to Gaia for her to raise, and Gaia takes him to a cave on Mount Aegaeon. Rhea then gives to Cronus, in the place of a child, a stone wrapped in swaddling clothes, which he promptly swallows, unaware that it isn't his son. While Hesiod gives Lyctus as Zeus's birthplace, he is the only source to do so, and other
