“supposition”是一个名词，表示基于有限证据或未经证实的猜测或假设。其核心含义是对某事的暂时性推断，通常带有不确定性，需要后续验证。
源自拉丁语 suppositio（置于下方），由 sub-（在...之下）和 ponere（放置）构成，后经古法语进入英语，词义逐渐演变为“假设”。
| 词汇 | 关键区别 |
|---|---|
| assumption | 更强调“未经质疑的默认接受” |
| hypothesis | 特指科学中可验证的假设 |
| presumption | 隐含“缺乏依据的武断推测” |
supposition 意为推测，猜测。以下是该词的详细解释：
supposition 通常用于以下语境：
that 连用。例如：The supposition that he had stolen the money turned out to be false.（他偷了钱的推测最终被证明是错误的。）on 连用。例如：The theory is based on the supposition that all men are created equal.（这个理论是建立在人人生来平等的假设基础上的。）supposition 与 assumption、presumption、conjecture 等词有一定的近义关系。其中，assumption 侧重于假设或推测的前提，常与 on 连用；presumption 则侧重于主观臆断，常含有贬义；conjecture 则更多地强调推测的不确定性。
supposition 的反义词为 fact（事实）。因为 supposition 指的是基于猜测或假设的推测，而 fact 则是指真实存在的事实。
