Things accepted as true without proof; beliefs or suppositions taken for granted as the basis for reasoning.
From Latin 'assumere' meaning to take up or adopt, composed of 'ad' (to) and 'sumere' (to take). The meaning evolved from physically taking something to mentally accepting ideas.
The word shares its root with 'consume' and 'presume' - all involving taking something. In logic and science, assumptions are deliberately chosen starting points, but in daily life, they're often invisible beliefs that shape our entire worldview without our awareness.
