Sense: adjective/1
'Apocalyptic' is stronger than 'catastrophic' because it suggests not just terrible damage, but a vision of final collapse or the end of life as we know it. 'Catastrophic' works for earthquakes, fires, and business losses, even when the scale is huge but not world-ending. 'Doomsday' is closer in meaning, but it is more fixed and often linked to religion, survival culture, or dramatic headlines about the last day of the world. 'Nightmarish' focuses on how frightening, chaotic, or unreal something feels, even if no one thinks the world will actually end. A flood can be catastrophic, a preacher may give a doomsday message, a war film may look apocalyptic, and a crowded hospital can feel nightmarish.

Etymology
Comes from 'apocalypse' plus the adjective ending '-tic'. The older root goes back to Greek 'apokalyptikos' and related words meaning 'uncovering' or 'revealing'. In early English, 'apocalyptic' was first used in religious writing about divine revelation and the last days. Later it broadened to describe anything that seems like the end of the world or predicts overwhelming destruction.
