1. In a sentence such as 'Do you want any more coffee?', the words 'any' and 'more' are two different words, and must be written separately. 2. You can also use 'any more' as an adverb meaning 'any longer', as in: 'She doesn't love him any more'. Some people write this as one word: 'She doesn't love him anymore'. However, it isn't necessary to make this one word. So, if you are not sure about the difference, it seems a sensible policy to always write 'any' and 'more' as two words. If you write them as two separate words, it will always be correct.

I hope this will help you: http://www.grammarly.com/handbook/grammar/adjectives-and-adverbs/13/anymore-vs-any-more/ Good luck! :)
