If I had penny for everyone who asked this question, I'd be a millionaire by now! In fact, the answer is incredibly simple. The word 'another' is just 'an' and 'other' written as one word. That's all. an + other = another 'A' or 'An' means 'One', so the word 'another' means 'one other'. So, just as we use the article 'a' or 'an' before singular countable indefinite nouns, we also use 'another' before singular countable indefinite nouns. A man ---> another man A book ---> another book If the noun is plural, we use 'other' ---> other countries If the noun is uncountable, we use 'other' ---> other information If the noun is definite, we use 'other' ---> the other house, my other sister Simple, isn't it?

Other -is different Another is for one more for e.g. May I have another piece of cake, please?
