This week's writing prompt is a language seeking exercise. While this won't launch you into drafting a great chapter or story, it just may help make that story about a large rabbit, for example, a bit better.
We all fall victim to the cliché, especially when stuck. For a way clear of this sinking ship I offer Roy Peter Clark's sage advice to not throw the baby out with the bathwater. Rather than fleeing like rats from a sinking ship, he tells us "don't be afraid to a take a cliché and tweak it. A bit of improvisation can take a stale phrase and bring it back refreshed."
Go back through whatever you're working on and seek out the clichés lurking in there. Write each cliché "on a piece of paper and list words or phrases that come close to the same meaning." Many of the options you craft will work while others will absolutely not. "No matter. You will need examples that do not work in order to find one that illuminates your meaning in an original way."
