When reporting discoveries in recreational linguistics, the careful logologist always specifies the stockpile of words he has used. The most convenient and widely-available stockpile of words are, of course, found in dictionaries. Unfortunately, dictionaries are not always easy to search through for words with certain characteristics, and various types of word lists have been compiled to make the task easier. One of the commonest ways to rearrange a dictionary is to list together all words of the same length. Within each length, words are then listed alphabetically; sometimes (in positional word lists) the alphabetization is done not only on the first letter, but on each of the letters in turn.
