Missi is a name, maybe not legal in this case.
Miss,
mis,
mi (do, re, mi)

If it isn't legal in scrabble it isn't legal here. So no Missi isn't allowed.

WOW! Good answers! I didn't expect that you guys would be so good at this riddle!

Take a dictionary. Remove all words that don't contain an I or an A (as only words containing those letters can have a 1 letter word in them). Now run an algorithm that picks a 9 letter word and then checks if any of the 8 letter words that it contains are in the dictionary. Now take any of those words that exist and check for 7 letter words it contains. Continue, stopping if at any point the word no longer contains an I or A.
Repeat for all 9 or longer letters in the dictionary.

And that doesn't even count the older dictionaries. There are probably twice what your algo found!
Scanning them in would be a byitch though....
