>The dessert, unfortunately, was unpeckable.<
Unpeckable is a new word for me,  I know peckish, (desiring something to eat, is how I'd quickly define it) and presume unpeckable is in-edible. if I could figure out how to start a string i was wondering if any one else was interested in word that exist  only with prefixes or suffixes.. 
I have never heard or read about anyone being  peck or pecking (well pecking as a kiss, yes, but that is whole different meaning) and feckless, is common enough, but Feck is never heard as word in US--nor is couth, but we do have uncouth louts.  and while i am sometimes discombobulated, I don't know as that i have ever been combobulated! 
or is this just a YART?
