The letters of a word rearranged in alphabetical order. When discussing a rack of letters or presenting a long word to unscramble, players usually recite the component letters in alphabetical order. For instance, the alphagram for ALPHAGRAM is AAAGHLMPR.
An alphagram of a word (or of any group of letters, such as a Scrabble rack) consists of those letters arranged in alphabetical order. For example, the alphagram of ABDICATE is AABCDEIT. Obviously, words which are anagrams have the same alphagram.
