‘Betoken’ is a formal word used to express the idea of symbolizing or signifying something. It was originally used solely in a negative context in relation to an ominous or foreboding warning of a future event. While it can still be applied in such a way, the word is now more commonly encountered in a professional context as an indication of something, whether good or bad.
