If you are trying to figure out the origin of Helicopter, you are using the wrong "partial words". The correct ones are helix and pteron. Helix-pteron became helicopter. "Helix" is a Greek word meaning "twisted" or "revolving" and "pteron" is a Greek word meaning "wing". Therefore helicopter means "revolving wing", referring to the rotor and top-blades of the helicopter.
The prefix meaning "wing" is "pter-" or "pterygo-".
Pter is a Greek word meaning wing like pterodactyl
