  The more formal, logical word: an assumption stated explicitly as the starting point of an argument or piece of reasoning, common in debate or academic writing.

Assumption and premise both mean an idea accepted as true without proof, but differ in formality. Assumption is the everyday, broader word, often made unconsciously. Premise is more formal: an assumption stated explicitly as the start of an argument, common in debate or academic writing.

这两个词都指未经证明就被当作真实的想法，但正式程度和用法不同：assumption 更口语化、范围更广，可以是无意识的、随口的想当然；premise 更正式，特指被明确说出、作为论证或推理起点的假设，常见于辩论或学术语境。这里不比较 assumption 表示“承担（责任、权力）”的义项。
