If I actually had a craw, here’s what would stick in it—the misuse of words. More specifically, I cringe when people use certain words to sound smarter than they are, only to reveal themselves as dolts.
Perhaps the most common of these offenses occurs with the lengthening—by a mere syllable, sometimes—of the correct word to make it the wrong one for the circumstances.
You ask: How about an example? Here are a couple:
“I begrudgingly lent my umbrella to that skunk of a sales manager.”
No, you would do so grudgingly. That is, you’d do it because it’s best for your company; your rep should look his best, even if he is a conniving, manipulative, malodorous cretin. And because your boss gently “suggested” it.
Now, you might begrudge someone her success or good fortune; that is, wish she had not benefitted in that way because of some prior altercation you two may have had.
The two words are somewhat similar in tone—that is, mean-spiritedness—but avoid doing things “begrudgingly.”
