This is a little experiment I carried out I don't know how many years ago. It has hung around in my send-out book for an eon -- time to call it a "Failure," another F word. 

The F Word

Follows from forbidden,

foreboding, forgiveness

of foresight into any fool's fortunes,

our forsaken formidable fun,

the foreshadowing foreshortened

forever, forthright, forested or un-,

unfurled, unfolding, unfathomed,

foretold or left forlorn,

what fevers are bodied forth,

formulaic, forked

and forded, found or dumbfounded,

flooded, no foreplay

forged or foregone.
