Wouldn't life be easier if spell checking software could help our dyslexic students? Well, of course it can help many less experienced writers, but it doesn't help those who confuse 'flower' and 'flour', or 'their' and 'there', or 'practice' and 'practise'. In fact, Word might even insert an error: in some versions of Word, if a person types 'I am going to do my piano practize', the software will automatically correct the misspelling to 'piano practise', which is wrong. The spelling should be 'practice' for the noun, and 'practise' for the verb, and 'piano practice' is a noun phrase.
