Anxiety is generally considered a bad thing, as illustrated by Merriam-Webster:
1 a : painful or apprehensive uneasiness of mind usually over an impending or anticipated ill
b : fearful concern or interest
Eagerness, on the other hand, is a positive anticipation (again, thank you Merriam-Webster):
2 : marked by enthusiastic or impatient desire or interest
And before anyone calls me on it: I'm aware that this is the second entry, but the first was labeled 'archaic' and 'obsolete'. Ergo, I used the current definition.
You know the most horrifying thing? I've even caught myself making this mistake! So, I've been trying hard to correct myself. And even though you probably shouldn't go around correcting people who say this (trust me, they don't like it), you can now rest easy in the knowledge that you are using correct diction (or intentionally using incorrect diction, if you like).
So, do you have any linguistic pet peeves? What are they? Do you point it out to people or let it slide (even though it's driving you insane on the inside)?
