Dheghom (Proto-Indo-European: *dʰéǵʰōm or *dʰǵʰōm; lit. 'earth'), or *Pl̥th₂éwih₂ (PIE: *pl̥th₂éwih₂, lit. the 'Broad One'), is the reconstructed name of the Earth-goddess in the Proto-Indo-European mythology.
The Mother Earth (*Dʰéǵʰōm Méh₂tēr) is generally portrayed as the vast (*pl̥th₂éwih₂) and dark (*dʰengwo-) abode of mortals, the one who bears all things and creatures. She is often paired with Dyēus, the daylight sky and seat of the never-dying and heavenly gods, in a relationship of contrast and union, since the fructifying rains of Dyēus might bring nourishment and prosperity to local communities through formulaic invocations. Dheghom is thus commonly associated in Indo-European traditions with fertility, growth, and death, and is conceived as the origin and final dwelling of human beings.
