exact

exact: [15] The adjective exact ‘precise’ and the verb exact ‘demand with severity’ have undergone considerable semantic divergence over the centuries, but they both go back to the same source, the Latin verb exigere (from which English also got essay, examine, exigent [15], and exiguous [17]). This, a compound of the prefix ex- ‘out’ and agere ‘lead, drive’ (source of English act and agent), meant originally ‘drive out’, but in due course it developed the metaphorical senses ‘demand’ (preserved in the English verb), ‘weigh accurately’, and ‘bring to completion or perfection’.

These last two were taken up adjectivally in the Latin past participle exactus, from which English gets exact.
=> act, agent, essay, examine

exact (adj.)

"precise, rigorous, accurate," 1530s, from Latin exactus "precise, accurate, highly finished," past participle adjective from exigere "demand, require, enforce," literally "to drive or force out," also "finish, measure," from ex- "out" (see ex-) + agere "drive, lead, act" (see act (n.)).

exact (v.)

mid-15c., from Latin exactus, past participle of exigere "require, enforce, demand, collect (money);" see exact (adj.). Older in English than the adjective and retaining the literal sense of the Latin source. Related: Exacted; exacting.

accurate, exact, precise, right, true, correct

这些形容词均含"准确的，正确的"之意。

accurate：指通过谨慎的努力达到符合事实或实际，侧重不同程度的准确性，与事实无出入。

exact：着重在质与量方面的准确，语气比accurate强。

precise：侧重极端准确，更强调细节的精确无误。

right：使用广泛，可与这些词中的correct换用，但常暗示道德、理解、行动等方面的正确。

true：暗指绝对准确，尤指复制品与原件丝毫不差。

correct：最常用词，主要指按一定标准或规则来衡量，没有谬误和差错或无缺点错误。
