Reconstructed words

*H₂epom Nepōts ('Descendant of the Waters') is a reconstructed Proto-Indo-European deity who dwells in waters, and whose powers must be ritually gained or controlled by a hero who is the only one able to approach it. The motif may come from swamp gas rising from swamps and igniting. It may come from the high levels of natural gas in Ukraine, the possible Proto-Indo-European homeland.

Proto-Indo-European mythology is the body of myths and deities associated with the Proto-Indo-Europeans, speakers of the hypothesized Proto-Indo-European language. Although the mythological motifs are not directly attested – since Proto-Indo-European speakers lived in preliterate societies – scholars of comparative mythology have reconstructed details from inherited similarities in mythological concepts found in Indo-European languages, based on the assumption that parts of the Proto-Indo-Europeans' original belief systems survived in the daughter traditions.

*Dʰéǵʰōm (Proto-Indo-European: *dʰéǵʰōm or *dʰǵʰōm; 'earth'), or *Pl̥th₂éwih₂ (PIE: *pl̥th₂éwih₂, the 'Broad One'), is the reconstructed name of the Earth-goddess in the Proto-Indo-European mythology.

Jehovah is a Latinization of the Hebrew יְהֹוָה‎ Yəhōwā, one vocalization of the Tetragrammaton יהוה‎ (YHWH), the proper name of the God of Israel in the Hebrew Bible / Old Testament. The Tetragrammaton is considered one of the seven names of God in Judaism and a form of God's name in Christianity.

Yahweh was an ancient Levantine deity who was venerated in Israel and Judah. Though no consensus exists regarding the deity's origins, scholars generally contend that he is associated with Seir, Edom, Paran and Teman, and later with Canaan. His worship reaches back to at least the Early Iron Age, and likely to the Late Bronze Age, if not somewhat earlier.

*Ḱérberos (Proto-Indo-European for "spotted") is the reconstructed name of the canine creature guarding the entrance to the Otherworld in Proto-Indo-European mythology. In a recurrent motif, the Otherworld contains a gate, generally guarded by a dog who could also serve as a guide and ensured that the ones who entered could not get out.

*Péh₂usōn ("Protector") was a proposed Proto-Indo-European pastoral god guarding roads and herds.

*Seh₂ul and *Meh₁not are the reconstructed Proto-Indo-European Sun deity and Moon deity respectively. *Seh₂ul is reconstructed based on the solar deities of the attested Indo-European mythologies, although its gender (male or female) is disputed, since there are deities of both genders. Likewise, *Meh₁not- is reconstructed based on the lunar deities of the daughter languages, but they differ in regards to their gender.

*H₂éwsōs or *Haéusōs (lit. 'the dawn') is the reconstructed Proto-Indo-European name of the dawn goddess in the Proto-Indo-European mythology.

*Dyḗus (lit. 'daylight'), also *Dyḗus ph₂tḗr (lit. 'father daylight'), is the reconstructed name of the daylight-sky god in Proto-Indo-European mythology. *Dyēus was conceived as a divine personification of the bright sky of the day and the seat of the gods, the *deywṓs. Associated with the vast diurnal sky and with the fertile rains, *Dyēus was often paired with *Dʰéǵʰōm, the Earth Mother, in a relationship of union and contrast.
