HI I will try and explain it better. I am meaning to write a function that takes a string, " apple" and eliminates the spaces at the start ONLY. called........ removeSpace :: String -> String I decided to use the function 'dropWhile' and another one 'isSpace' in the 'removeSpace' function. removeSpace:: String -> String removeSpace a = case dropWhile isSpace a of "" -> I get stuck here... I am not sure how to go about this function. Any ideas.

look at the examples of dropWhile usage you got from the first result
when you get when you google on dropWhile.
