Words in fantasy

What are some words that take you out of the story and words that keep you immersed? For me, I can't read a book that says something like "stupid" or "idiotic". These words have to be "foolish" or "reckless" to me in a fantasy setting haha. Words that keep me immersed are when characters mention something about "gods" (I love a good fantastical religion in worldbuilding) and "insufferable" or "vexing" instead of annoying. This might be a little nitpicky, but I also love it when "perhaps" and "quite" are written, but that's definitely more traditional. Oh, or even "mad" for "insane". Maybe I just gravitate to medieval-coded fantasy, but especially when there's not much technology and the world heavily relies on things like horses or there are places like taverns and inns, the modernity of language just takes me out of it.

Fantasy is fantasy, but I've been watching/reading Fourth Wing reviews (just a quick example) discussing the "modern" words that were used and I didn't really catch them since I listened to it as an audiobook. I have the e-book and there are so many examples.

This is NOT a means of bashing Fourth Wing or any other authors who use "modern" words, I am simply curious :)

So, what are yours? Words that keep you immersed and words that threaten a DNF?
