What does Naga mean?
From Sanskrit नाग (naga) 'snake, serpent', also denoting the semi-divine serpent beings (nagas) of Hindu and Buddhist lore. Note: classical Sanskrit lexicons record a secondary established sense 'elephant', and the deeper etymology of the word is itself uncertain; the primary and relevant meaning here is 'serpent'.
What does Chandra mean?
Chandra means 'moon' in Sanskrit, from a root meaning 'to shine,' and is the name of the Hindu lunar deity among the Navagraha. Used for boys in India (the god) and often for girls in the West.
