and for drake, it is just part of the "word morphing" we do to things. It is still dragon.
Quote:
In European mythology, a dragon is a serpent-like legendary creature. The Latin word draco, as in the constellation Draco, comes directly from Greek δράκων, drákōn. The word for dragon in Germanic mythology and its descendants is worm (Old English: wyrm, Old High German: wurm, Old Norse: ormr), meaning snake or serpent. In Old English wyrm means "serpent", draca means "dragon". Though a winged creature, the dragon is generally to be found in its underground lair, a cave that identifies it as an ancient creature of earth, like the mythic serpent, that was a source of knowledge even in Eden. Likely, the dragons of European and Mid Eastern mythology stem from the cult of snakes found in religions throughout the world.
