Don't look now, but language, always alive and evolving, has substituted new words for old for no reason. Most of these words and figures of speech have been around for years now, but bit by bit they've gone from being my own pet peeves to being the only way to say a thing. I don't know when, I don't know why--but I'm relearning how to speak colloquial American English.
It seems that we are all expected to use the word in quotes instead of the word it replaced:
When did a category become a “genre”?
When did a sidewalk become a “hardscape”?
When did a political stand become a political “stance”?
When did the populace become “folks”?
When did problems become “issues”?
When did lemon rind become “lemon zest”?
When did the woods become a “green belt”?
When did God become a “meme”?
When did “said” become “was like”?
When did reframing the question become "pushback"?
Maybe you can add a few others you've noted, particularly from television commentators. I don't want to be the only one pushing the envelope here (by the way, what envelope?).
