I've read that the author of Peter Pan, J. M. Barrie, kept ordering Brussels sprouts but never ate them. His explanation was that he found saying the words irresistible.
The vegetable was eminently resistible, but the words were just too tempting not to say. Again and again. And again.
My late mother, a talented writer, lamented that she couldn't resist the word nifty. She found it not very nifty to have this nifty word in every other sentence.
My second editor for The Voice of Thunder noted that I have overused the word now. Now then, why now here and now there when we know this happened long ago and the tense is past? Now go and slash ‘em now-words wherever you can. She was right.
They’re known as tick words. Most of us mortals have them. You don’t have to be a writer to notice this in yourself.
But writers must pay heed. Resist, and order something else. Maybe something you’d like to eat.
