Gemini

gemini "Zwilling"

Etymology 1

Borrowed from Latin geminī, plural of geminus “Zwilling”, calque of Ancient Greek Δίδυμοι (Dídumoi).

Etymology 2

Perhaps identical with the above (compare Latin ēdepol (“by Pollux”), ēcastor (“by Castor”)), but perhaps more likely distinct in origin: compare Dutch jemenie, jemie, German gemine, jemine, Czech jémine, all ultimately shortened from Latin Iēsū domine (“O Lord Jesus”).
