Simplified etymology
Helicopter was borrowed in the late 19th century from French, before practical helicopters appeared. The French word was formed from Greek helix, "spiral," and pteron, "wing."
Etymology
Borrowed from French hélicoptère, from Ancient Greek ἕλιξ (hélix, “spiral”) + πτερόν (pterón, “wing”). Doublet of helicopteron. By surface analysis, helico- + -pter. The dragonfly sense is from a dragonfly's ability to hover and fly in any direction, like the flying machine.
