Spelling is not hard to learn. Everyone can do it. Fortunately, learning to spell is much easier than learning to walk; it involves no bloody knees or falling down stairs!
English spelling is not problem-free for anyone. In some languages, the sound of a word and the way you spell it is very close, and you pretty much write down what you hear. Also, you can usually tell how to pronounce a word by looking at it. So spelling in some language is pretty easy. This just isn’t so in English.
