[Haskell-beginners] Read just one word from input

Hello Haskellers,

Is there really no way to read input word-by-word? E.g., if user types

  1 2 3 4 5

function (let's call it getWord :: IO String) should first return "1",
then "2", and so on.

The main idea behind that is if user entered more values then required,
they won't be lost but instead consumed by subsequent reads (calls to
getWord). That's how scanf() in C and 'cin >>' in C++ behave, and I'm
quite surprised that I can't do that in Haskell.
