Pronunciation

  • 5th-century BC Attic: /del.pʰy̌ːs/[1]
  • 4th-century AD Koine: /ðelˈɸys/[1]
  • 10th-century Byzantine: /ðelˈfys/[1]

Forms

δελφῡ́ς (delphū́s) f (genitive δελφῠ́ος); third declension[1] Doric δελφύα, according to Gregory of Corinth, perhaps after μήτρα (mḗtra).[2][3][4]

Etymology

It goes back to Proto-Indo-European *gʷelbʰ- (“womb”), perhaps as a u-stem *gʷelbʰ-u-.[1][2] The labiovelar became /d/ before /e/, and van Beek notes that this palatalization took place before the dissimilation of labiovelars next to a labial.[2][5]

The closest cognates are Indo-Iranian: Sanskrit गर्भ (gárbha, “womb, embryo”) and its Avestan counterpart for “womb”, which match the o-grade gloss δολφός (dolphós, “womb”) in Hesychius, while the zero-grade neuter gərəbuš- (“young animal”) suggests that δελφύς may also have been an s-stem.[2][3] The Germanic words for the lamb and calf, such as Old High German kilbur (“ewe lamb”) and Old High German kalb (“calf”), begin with /k/, which does not fit a labiovelar, so Beekes keeps them apart unless a dissimilation is assumed; the DGE includes them.[2][6] Chantraine explains the gloss, with its initial dental, as a phonetic change of *δελφός (delphós).[3]

The word explains ἀδελφός (adelphós, “brother”), “born of the same womb”, and the same root is seen in δελφίς (delphís, “dolphin”) and δέλφαξ (délphax, “young pig”).[3][6][5] The ancient lexica already drew that conclusion: Photius and the Lexica Segueriana gloss it as “womb”, the source of the word for brother, and the Etymologicum Magnum adds that the womb makes those born from it brothers.[7][8][9][10]

Earliest recorded meaning

Its first record is in the Hippocratic treatise on sterility, which speaks of an abscess in the womb.[6][4][11]

Semantic evolution

It remained a rare and isolated medical and learned word, replaced by μήτρα (mḗtra).[3] Aristotle uses it in his History of Animals, Lycophron in his Alexandra, and later Rufus, Pollux and Athenaeus.[4][6][11] The Byzantine lexica gloss it as womb or belly.[9][10]
