STORY:
The land of Dictionaria was once a utopia where all words lived together in perfect harmony. Words respected each other and the big words always found a place among their smaller compatriots. The words worked together to weave letters into poetry and literature.
But just as every cheery summer is followed by a chilly winter, the good days of Dictionaria seem to be nearing an end as the newly powerful invaders from the dark depths of Chatsville go about destroying the natural beauty of Dictionaria. It started rather harmlessly when Laugh, Out and Loud found themselves marginalized as the petty thief Lol found his feet in Dictionaria. Brb came in and usurped the position long enjoyed by Be, Right and Back. There was almost no unease when these small time criminals began gaining recognition. But the worst was almost knocking on the door.
When Yolo and Twerking came charging through the gates, little did the natural words know that everything in Dictionaria would never be the same again. The popularity of these thugs grew by and large, and slowly they began claiming to be natural residents of Dictionaria. Led by the notorious mob boss Swag, the Usurpers from Chatsville have now decided to wipe out the older words of Dictionaria and claim the entire land as their own.
Swag has entrusted the task of complete domination to his two trusted henchmen - Xoxo, the sweet tongued monster and Asap, the swift executioner. Swag has ordered Xoxo and Asap to eliminate all words in an alphabetical order, killing words starting with a particular letter every day. Aardvark will be one of the first to go and millions more will soon follow.
Now, the henchmen are ruthless but not so bright and some of the words of Dictionaria have realized that they can escape the massacre simply if they manage to pass off as another word on their predestined day of execution.
These words are lucky to be born with such characteristics that they can contort their bodies to make their head appear where their foot is, and their foot appear where their head is. And once they escape their execution, they can live on because the henchmen will not remember which words have escaped their execution. These words hope to avoid death and one day drive out the Usurpers of Chatsville, but they need to know who their leader would be. As the natural words were respectful of those bigger than them, their leader would be the tallest one among them.
Who do you reckon will survive the massacre and lead the survivors?
PUZZLE:
Find the longest word in the English language that can be morphed into another word simply by switching its first and last letter. The word cannot have the same first and last letter. And the word cannot be an abbreviation or contraction. The word should be found on Dictionary.com and words that are valid in Scrabble are not counted if they do not appear on Dictionary.com.
EDIT:
Dictionary.com is the bible of the residents of Dictionaria (hence the inspired name) and all those who seek to nominate non-existing words as the leaders are distrustful pagans. Be gone infidels!
