In a manner suggesting the end of the world, catastrophic events, or divine revelation; with apocalyptic intensity or character.
From Greek 'apokalyptein' (to uncover, reveal) + '-ical' + '-ly'. The root originally meant 'revelation' in religious texts before shifting to mean 'catastrophic' in English.
The word 'apocalypse' comes from Greek meaning just 'reveal'—it originally meant unveiling divine truth, but modern English twisted it into doom and gloom, which says something about how our pessimism hijacks ancient words.
