A person who predicts disaster or catastrophe; someone who habitually expects and announces bad outcomes.
From 'doom' + 'sayer' (Old English 'secgan', meaning 'to say'). This compound noun emerged in English to label people who constantly prophesied negative futures.
Doomsayers have existed throughout history—from Cassandra in Greek mythology to modern climate scientists—and the irony is that being right doesn't make you popular; people resent messengers of bad news regardless of accuracy.
