It’s a rule of thumb for any writer to follow Strunk’s advice and “omit needless words.” That’s easier said than done. Sure, you know which filler words to cut, and you know how to hunt down those pesky weasel words. But sometimes, sheer editing isn’t enough.
Your writing can still suffer after you’ve gone through your piece seven times. Why? Because you’re likely using crutch words and have become blind to them. While this doesn’t seem like a big deal, it can bog down your writing.
