What does Draco mean?
Latinized form of Greek Drakon (Drakwn), meaning 'dragon' or 'serpent'. Borne by the 7th-century BCE Athenian lawgiver (source of 'draconian'). Note: one scholarly etymology derives drakon from the aorist stem drak- 'to see clearly', giving an underlying sense 'sharp-sighted'; this is a plausible deeper derivation but a minority reading, and the established dictionary meaning remains 'dragon/serpent'.
What does Cosmo mean?
