A long-forgotten etymological tidbit from Paul.
If you asked most people to break down the world "helicopter" into its word parts, most people would guess "heli" and "copter." This makes since, initially, since we now use "heli-" as a word part in things like "helipad" and "copter" now means something on its own. However, the word is actually divided in a way I find surprising. The first part is the Greek helik, which has associations with spinning and gives us our word "helix." The second part is pter, which means "wing" and is probably most familiar to English speakers in words like "pterodactyl."
And I think this is fucking rad. Hey, remember Paul?
