I view reading fantasy/sci-fi stuff as "this work of fiction is being translated into english so that I can understand it, meaning some phrases should not be taken literally" lord of the rings style, and then I meet people who nitpick every word or phrase that "shouldn't exist in this story" and I'm like wow you guys are truly miserable and unimaginative. and also you tend to assume that english words all popped up in the 19th century and you never bother to check the etymology of the words you're claiming "shouldn't exist in this universe"

like sorry but in an apocalyptic alternate-universe earth, the phrase "train of thought" is plausible even in a world without locomotives, because the word "train" comes from the 14th century, and it meant "to drag"

that's why we call dress trains "trains". because they drag. the word wasn't invented for locomotives.

y'all say shit so definitively like idk man I think it depends. the english language is OLD AS FUCK. a lot of words you believe are modern just aren't
