Helico means spinning and pter means pter

Maybe you were just deliberately baiting for this, but no!

Helicopter's etymology actually breaks down into helico and pter. Helico being cognate with helix, and pter being "flying", from the same root as pterodactyl (flying finger).

Super interesting.

Does that mean that we're pronouncing either helicopter or pterodactyl wrong? We don't say the 'pter' parts the same way I think?

nah there's no "wrong" for a common native pronunciation. but for silent p- words specifically, the /pt/ and /ps/ consonant clusters just don't occur at the start of words in English. so the p goes silent in those words. pterodactyl, psychology. but in languages like Greek and German they do occur!

I thought heli is more like a screw. (Not claiming that it is, but that was my understanding)

The word is not "heli" though. It's "helico".

Like in the helicoprion (a shark with a spiral think on it's mouth) or a helicograph (a tool to draw spirals).

Or, y'know, a helix.

Yes, that is where it comes from.

Doesn't change the fact that the word helicopter splits into "helico" and "pter" with the later meaning wing or feather in greek.

It's a helico-pter "spiraling wing", not a heli-copter.

It’s a helico-pter “spiraling wing”, not a heli-copter.

TIL

The dictionary definition is "Anything twisted, winding, or spiral." but an inference can be made

Pterodactyl - Pter Finger!
Then there's choleodoptera and lepidoptera.
