Elmore Leonard: Do we use too many exclamation marks?, by Finlo Rohrer (BBC)
Elmore Leonard has died at the age of 87. The crime novelist really didn’t like exclamation marks, notes Finlo Rohrer.
His 10 rules of writing from 2001 are arguably as famous as any of his novels. Point five reads: “Keep your exclamation points under control. You are allowed no more than two or three per 100,000 words of prose.”
He wasn’t the only enemy. “Cut out all these exclamation points,” F Scott Fitzgerald urged. “An exclamation point is like laughing at your own joke.”
There’s even a word, bangorrhea, that describes their overuse.
