I'm not making it up -- honest! Around here, all the supermarkets have "Appetizing Departments" (AKA "Appy"), where you go for your potato salad, cole slaw, whitefish, etc.
I always thought that was what it was called until my friend said that it was entirely strange.
Do you guys even have smoked whitefish in the middle of the country? 'Cause if you don't, maybe that's why you don't have the word to go with it.
"Something appetizing" is correct, but it doesn't have the specific meaning of "appetizing" (the noun). For all you know,"something appetizing" could be a bowl of chicken soup.
Which certainly is appetizing, but isn't Appetizing.
