i once read an article in which about 8-9 words were mentioned...



I would be surprised if there are 8 "legitimate" words of 26 letters.

A 26 letter word with each letter occuring only once would only have 5 vowels + y. I'm too lazy to do the exact anaylsis but the word would have to have more than one sequence of 5 or more consonants like AcccccEcccccIcccccOcccccUY or ccccccccccccOUcccccAcccccIEcccccccccccY etc. Not going to be very pronouncable is it?
