aeroplane

> plane and aeroplane
plane and aeroplane mean the same thing, both referring to a "a machine that can fly and is used to carry people and goods". In modern usage plane is the usual term, as in "The plane took off on time" and "nearly miss the plane". Aeroplane is slightly old-fashioned or unduly formal, as in "Her elderly parents say that they refuse to travel by aeroplane". The American English spelling is airplane. Note that plane is not spelt with an apostrophe although it is a shortened form.
