I did a search and couldn't find the answer to this, so I thought I would post the question. Would it be all right to use obsolete or archaic words as nouns in a fantasy setting? Sometimes even adjectives and verbs (that aren't recognized anymore) seem like they would make the perfect name, but I wonder if using a word like that is taboo? (Note that I'm not thinking of any words that would be recognizable to most people.) I hope this isn't a stupid question, and if so I apologize in advance.
