In Hesiod's Theogony, Aphrodite is born off the coast of Cythera from the foam (aphrós) produced by Uranus's genitals, which his son Cronus has severed and thrown into the sea. In Homer's Iliad, however, she is the daughter of Zeus and Dione. Plato, in his Symposium 180e, asserts that these two origins actually belong to separate entities: Aphrodite Ourania (a transcendent, "Heavenly" Aphrodite) and Aphrodite Pandemos (Aphrodite common to "all the people"). Aphrodite had many other epithets, each emphasizing a different aspect of the same goddess, or used by a different local cult. Thus she was also known as Cytherea (Lady of Cythera) and Cypris (Lady of Cyprus), because both locations claimed to be the place of her birth.
Hesiod derives Aphrodite from aphrós (ἀφρός) "sea-foam", interpreting the name as "risen from the foam", but most modern scholars regard this as a spurious folk etymology. Early modern scholars of classical mythology attempted to argue that Aphrodite's name was of Greek or Indo-European origin, but these efforts have now been mostly abandoned. Aphrodite's name is generally accepted to be of non-Greek, probably Semitic, origin, but its exact derivation cannot be determined.
Scholars in the late nineteenth and early twentieth centuries, accepting Hesiod's "foam" etymology as genuine, analyzed the second part of Aphrodite's name as *-odítē "wanderer" or *-dítē "bright". Michael Janda, also accepting Hesiod's etymology, has argued in favor of the latter of these interpretations and claims the story of a birth from the foam as an Indo-Europeanmytheme. Similarly, Krzysztof Tomasz Witczak proposes an Indo-European compound *abʰor- "very" and *dʰei- "to shine", also referring to Eos. Other scholars have argued that these hypotheses are unlikely since Aphrodite's attributes are entirely different from those of both Eos and the Vedic deityUshas.
A number of improbable non-Greek etymologies have also been suggested. One Semitic etymology compares Aphrodite to the Assyrian barīrītu, the name of a female demon that appears in Middle Babylonian and Late Babylonian texts. Hammarström looks to Etruscan, comparing (e)prϑni "lord", an Etruscan honorific loaned into Greek as πρύτανις. This would make the theonym in origin an honorific, "the lady". Most scholars reject this etymology as implausible, especially since Aphrodite actually appears in Etruscan in the borrowed form Apru (from Greek Aphrō, clipped form of Aphrodite). The medieval Etymologicum Magnum (c. 1150) offers a highly contrived etymology, deriving Aphrodite from the compound habrodíaitos (ἁβροδίαιτος), "she who lives delicately", from habrós and díaita. The alteration from b to ph is explained as a "familiar" characteristic of Greek "obvious from the Macedonians".
