I'm very sorry, I don't believe that word is in my language. Bogus?

( From a time before modern slang, Dany's unable to confidently decide what the word means. Obviously, it speaks of the validity of the words, but to a positive or negative degree? )

I have a difficult time believing the written words. Tales are passed around to children and weak men, tales meant to control them and bring them fear. Are these such words?
