Gemini is the name of the third sign of the zodiac and a constellation which represents twins Castor and Pollux, who had the same mother, Leda, but different fathers: Pollux was the son of Zeus while Castor's father was the Spartan king Tyndareus. The name comes from Latin geminī meaning "twins" from geminus (twin; double, paired), possibly deriving from PIE *yem- (to pair, match). Origin: Proto-Indo-European Male forms: Geminus (Ancient Roman)…
