helicóptero
/eliˈkobteɾo/ · B1 · noun · m
helicopter
🚁 helico (spiral, as in helix) + ptero (wing, as in pterodactyl) = spiral wing
It comes from Greek hélix (spiral) + pterón (wing): a machine with wings that spin round. In Spanish the h is silent and the stress falls on -có-, so it sounds like eli-KOP-te-ro. It is masculine: el helicóptero.
