Because he cannot read the elvish script, he uses the Latin characters (a, b, c) instead. Having done this, he notices a pattern with the Elvish words. In any given word, consonants are always be followed by vowels. After a vowel, there may be either a vowel or a consonant (or nothing). The vowels are the characters \"a\", \"e\", \"i\", \"o\" and \"u\".\u003c/p\u003e \n\n\u003cp\u003eAlso note that the letter \"n\" is an exception.
