I would like to understand the formation of Latin compound words through the example of the word "helicopter". This obviously has a Greek origin, and I would like redo the construction with two Latin words.
I would translate helix as vertex and pteron as ala. But how do I combine the two analogously to the Greek helico-pteron? I'm not sure what to do with the first word. Can I go with vertici-ala? Or is this a situation where natural compounds are impossible although Latin does allow compound words?
