Sign, omen, portent name that which gives evidence of a future event. Sign is a general word for whatever gives evidence of an event—past, present, or future: Dark clouds are a sign of rain or snow. An omen is an augury or warning of things to come; it is used only of the future, in general, as good or bad: birds of evil omen. Portent, limited, like omen, to prophecy of the future, may be used of a specific event, usually a misfortune: portents of war.
