Etymology Origin:
The word traces back to Latin assumptio ("a taking up"), from assumere ("to take up, adopt"). The prefix ad- (as-) merges with sumere ("to take"), reflecting the idea of "taking toward oneself." Over time, it evolved to signify both literal acts of taking (e.g., power) and abstract acceptance of unproven ideas. The theological sense (Virgin Mary's ascent) emerged in Late Latin.
