[French hélicoptère : Greek helix, helik-, spiral. See helix + Greek pteron, wing. See -pter.]

Word History: The origin of the word helicopter is apparent only upon due recognition of its Greek ancestors. Helicopter was borrowed from the French word hélicoptère, a word constructed from Greek heliko- and pteron,"wing."Heliko- is a form of helix,"spiral," that combines with other words and word forms to create new words. The consonant cluster pt in pteron begins many Greek words but relatively few English words, so English speakers who are unfamiliar with Greek do not think of the word's elements as helico-pter. At least some English speakers have analyzed the word into the elements heli-copter, as is shown by the clipped form copter.
