IPA: /fɔːrˈtoʊkənɪŋ/
KK: /fɔrˈtoʊkənɪŋ/
A sign or indication of something that will happen in the future.
The dark clouds were a foretokening of the storm to come.
Foretokening → It is formed from "fore-" (meaning before) and "token" (from Old English *tacn*, meaning a sign or symbol) and the suffix "-ing" (indicating the action or process). The word "foretokening" refers to the act of indicating or signaling something before it happens, essentially a sign of what is to come.
Think of a 'sign' ('token') that comes 'before' ('fore-') an event — that's what foretokening means.
