I like words / phrases that are palindromes ("A man, a plan, a canal Pamana" for instance, though the fact that you have to put spaces and punctuation in bothers me... I'd rather write it "AMANAPLANACANALPANAMA"). I also like letters that flip on their own vertical axis perfectly (A, M, O, I, V, H, U, W, X, Y, T). Words made only out of these letters are cool, too. TAM, MAT, VAT, YAM, etc.
So it should reason that my favorite word in the entire world is "mom" because it adheres to both. In reality, that word doesn't do anything for me. I think I like the concepts in the abstract better than the words that embody those concepts.
