Etymology tree Proto-Indo-European *nebʰ- Proto-Indo-European *-os Proto-Indo-European *nébʰosder. Proto-Italic *neptūnos Latin Neptūnusbor. Middle English Neptune English Neptune From Middle English Neptune, Neptunus, a borrowing from Latin Neptūnus, possibly from Proto-Indo-European *nébʰ-tu-s (“damp, cloudy”) (source of Ancient Greek νέφος (néphos), Sanskrit नभस् (nábhas), etc.), with the sense of "wet, moist." Puhvel, however, connects it with Proto-Italic *nepōts from Proto-Indo-European *népōts by analogy to Portūnus, cognate with Vedic Apām Napāt and Avestan Apąm Napāt, Child (cf: neve, nephew) of the Water as part of an Indo-European 'Fire in the Water' myth.
