doomsday means concerned with or predicting future universal destruction.
doomsday is pronounced /ˈduːmz.deɪ/.
Why “doomsday” is a great word
The specific, often personified day of final divine judgment or ultimate catastrophe. From Middle English domes dai, from Old English dōm ("judgment, decree") + dæg ("day"), literally "Judgment Day"; compare Old Norse dómsdagr. Unlike "apocalypse," which emphasizes the catastrophic events and revelatory nature of the end, or "eschaton," the theological concept of final events, doomsday is the terminus itself. It is the stark, unblinking clockface reading midnight, the last page of a calendar curling in flame, and the cold click of a Geiger counter in an abandoned city—the moment when all accounts are settled, not in process or prophecy, but in perfected, silent fact.
