Σεμέλη

• From the ancient Greek words σείω (seíō, “shake”) +‎ μέλος (mélos, “member, part of the body”), because she was shaking when she saw Zeus coming to her as fire.
• Otherwise from a Thracian *semela, *semla (“earth”) continuing Proto-Indo-European *dʰéǵʰōm (“earth”), thus an Earth Goddess. See also Phrygian Ζεμελω (Zemelō) and ζεμελως (zemelōs, “man”), Lithuanian žemė, Latvian zeme, Bulgarian земля (zemlja), Russian земля (zemlja), and Δημήτηρ (Dēmḗtēr).^[1]
