rest

Compared meaning: a short rest from hardship or tiredness (noun).

比较义项：从劳累或困境中获得的短暂休息（名词）。

• rest 本词

  The general, neutral word for stopping an activity to relax or sleep and recover energy; it does not imply escape from hardship, and it is common as both a noun and a verb in everyday speech.

  「rest」是中性、通用的词，指停止活动以放松或睡觉、恢复体力；并不暗示是从困境中获得解脱，日常口语中既可作名词也可作动词。

  After the long hike, we sat down on a bench to rest for a while.

  长途远足后，我们坐在长椅上休息了一会儿。

• respite

  Means a short, often welcome relief specifically from something difficult, stressful or exhausting; more formal than rest, usually a noun, and typically followed by 'from' plus the hardship.

  「respite」指从困难、压力或劳累中获得的短暂而通常令人欣慰的缓解；比「rest」更正式，通常只作名词，常与「from + 困境」搭配使用。

  The short break gave workers a welcome respite from the heat.

  短暂的休息让工人们从酷暑中得到了片刻宝贵的喘息。

Rest and respite both mean a short break. Rest is neutral, for stopping to relax or sleep; it can be a verb and does not imply hardship. Respite is more formal: relief from something difficult, usually with 'from'. Rest's other meaning, 'what remains', not compared.

这两个词都表示“短暂休息”，但语气和用法不同：rest是日常中性词，只是停下来放松或睡觉，不一定与困难处境有关，且可作动词；respite更正式，特指从艰难、压力或劳累中获得的缓解，通常只作名词，常与“from”连用。这里不比较rest的其他义项，例如“其余、剩下的部分”。

Compared meaning: the part that is left over (noun).

比较义项：剩余的部分或余量（名词）。

• rest 本词

  The most common, everyday word for what is left; neutral in tone, used for a remainder of any size, often with 'of' (the rest of the pizza).

  最常见、最口语化的“剩余部分”说法，语气中性，可指任意大小的余量，常与 of 连用（the rest of the pizza）。

  She ate half the pizza and saved the rest for breakfast.

  她吃了一半披萨，把剩下的留到早餐吃。

• residue

  A small physical trace left behind after most of a substance is used, removed, or reacted; often implies dirt, stickiness, or something unwanted.

  指某种物质大部分被使用、清除或发生反应后残留下的少量痕迹，常带有脏污、粘腻或令人不悦的意味。

  Wipe off the sticky residue the tape left on the wall.

  把胶带留在墙上的粘性残留物擦掉。

• residual

  A technical noun for a small leftover amount, common in finance, accounting, or statistics; the word is more often used as an adjective (residual value) than as this noun.

  指少量剩余额的专业名词说法，常见于财务、会计或统计语境；该词更常作形容词使用（如 residual value“剩余价值”）。

  The budget report showed a small residual of unspent funds.

  预算报告显示还有一小笔未花完的剩余资金。

• remainder

  A formal word for what is left after part has been used, removed, or subtracted; the standard term for the leftover number in a division.

  指某部分被使用、去除或相减后剩下的部分，语气正式，也是除法运算中“余数”的标准说法。

  Divide 17 by 5 and you will get a remainder of 2.

  17 除以 5，余数是 2。

Rest, residue, residual and remainder all mean what is left. Rest is common and neutral, for any leftover. Residue is a small physical trace, often unwanted. Residual is technical, used in finance, more often an adjective. Remainder is formal: a division's leftover number.

这四个词都表示“剩余的部分”，但语气和场合不同：rest 最口语、最通用；residue 强调物质上残留的少量痕迹，常带负面色彩，如粘腻的残留物；residual 在此指名词“剩余额”，多用于财务、会计、统计等专业语境，它更常见的用法其实是形容词“剩余的”；remainder 语气正式，是数学除法中“余数”的标准说法。这里不比较 rest 表示“休息”的动词义。
