seat

Compared meaning: a place to sit (noun).

比较义项：座位（名词）。

• place

  Informal and general: an available spot to sit, not necessarily a designated chair; common in phrases like 'find/save a place'.

  较为口语、笼统：指一个可以坐下的空位，不一定是专门的座椅；常用于“找/占一个位置”这类说法。

  Can you save me a place next to you at the concert?

  你能在音乐会上帮我占一个挨着你的位置吗？

• seat 本词

  The standard, concrete word for a chair or place designed for sitting, used in formal and everyday contexts alike, e.g. booking or taking a seat.

  标准、具体的说法，指专门供人坐的椅子或座位，正式和日常场合都常用，比如预订座位或就座。

  Please take a seat while you wait for the doctor.

  请坐下等候医生。

Place and seat both can mean a spot to sit. Seat is the standard word for an actual chair, used formally and casually. Place is more casual, just an available spot to sit. This does not compare place meaning 'location', or seat's other meanings.

这两个词在“供人坐的地方”这个意思上很接近，但 seat 是最直接、最常用的说法，指具体的座椅或座位；place 更宽泛、较随意，只是指“可以坐下的位置”，不强调是专门的座椅。这里不比较 place 的“地方、场所”这一更常用义项，也不比较 seat 的“使就座”动词义、“席位（议席）”或“所在地”等其他意思。

Compared meaning: the buttocks (noun).

比较义项：臀部（名词）。

• seat 本词

  A mild, slightly formal or polite way to refer to the buttocks, often used by doctors, tailors, or in descriptions of clothing fit; rarely used casually among friends.

  指臀部的一种较委婉、略正式的说法，常用于医生、裁缝或描述衣物合身度的场合；朋友间随意聊天时较少使用。

  The doctor asked him to lie on his side and examined the seat area.

  医生让他侧躺，检查了臀部区域。

• bottom

  The everyday, casual word for the buttocks, commonly used with children or in informal conversation; can sound childish or too blunt in formal settings.

  是表示臀部最常见、最随意的口语说法，常用于和小孩说话或非正式场合；在正式场合使用会显得幼稚或过于直白。

  She slipped on the ice and landed right on her bottom.

  她在冰上滑倒，正好摔在屁股上。

Seat and bottom both can mean the buttocks, but seat is a milder, slightly formal word, often used by doctors or tailors. Bottom is the everyday, casual word, common with children or informal talk. This does not compare bottom meaning 'the lowest part'.

两词在“臀部”这个意思上接近，但 bottom 更随意、口语化，seat 略显委婉或正式，常见于医生诊室、裁缝等场合。这里不比较 bottom 的“底部、末端”这一常用义（如例句中包包的底部）。
