dromedary: [14] The dromedary, or onehumped camel, got its name from its swiftness of foot. The word comes via Old French dromedaire from late Latin dromedārius, an adjective formed from dromas, the Latin term for ‘camel’. This in turn was derived from the Greek dromás ‘runner’, a close relative of drómos ‘running, course’, which is the source of the -drome in such English words as hippodrome, aerodrome, and palindrome.
