So I know it's generally good practice to avoid expressions that are anachronistic or that refer to things that don't exist in a fantasy world. (E.g. A character in a medieval setting shouldn't say "a lightbulb came on" in reference to having an idea.) But I'm stuck on what appears to be a grey area. We now commonly use the word "gulag" to refer to a prison or labor camp, typically a very bad one. But the word originally comes from a Soviet acronym, a fact most people don't know. So can you use the word gulag in a fantasy setting because of its common meaning? Or would that be anacosmic (I invented a word!) given the word's specifically Soviet origins?
