crown

Compared meaning: the highest point of something (noun).

比较义项：某物的最高点／顶部（名词）。

• crown 本词

  Crown names the rounded top of a head, hill, tooth, or road surface; more formal or technical than 'top' and rarely used for flat-topped objects.

  crown 指头顶、山顶、牙冠等呈圆突状物体的最高点，比 top 更正式或专业，很少用于描述顶部平坦的物体。

  The dentist repaired a chip in the crown of her front tooth.

  牙医修补了她门牙牙冠上的一处缺损。

• top

  Top is the plain, all-purpose word for the highest part of anything, with no shape or size implied, and is far more common in everyday speech than the others.

  top 是最通用、最日常口语化的词，指任何东西的最高部分，不隐含形状或大小，使用频率远高于其他三个词。

  Put the vase on top of the bookshelf, not underneath.

  把花瓶放在书架顶部，不要放在下面。

• peak

  Peak names the sharp, pointed top of a mountain or similar rise, and also extends figuratively to the highest point of an activity, unlike the other three.

  peak 指山峰等尖锐突起的最高点，也可比喻性地指某项活动的最高点（巅峰），这一点是另外三个词所没有的。

  Clouds hid the peak of the mountain from view all morning.

  整个上午，云层都遮住了那座山峰，让人看不见它。

• crest

  Crest is the top edge of a hill, wave, or ridge, often describing reaching or going over a rise, and is not used for small everyday objects.

  crest 指山丘、海浪或山脊的顶端，常用于描述到达或翻过一处隆起地形，不用于描述日常小物件的顶部。

  The road disappeared over the crest of the hill ahead of us.

  道路在我们前方翻过山顶后就看不见了。

Crown, top, peak, and crest all name a highest point. Crown is formal, for a head, hill, or tooth. Top is the plain, general word. Peak is a mountain's sharp point, also figurative. Crest is a hill, wave, or ridge top. These have other senses.

这四个词都可以指某物的最高点，但常搭配的对象和语域不同：crown 多指头顶、山顶或牙冠这类呈圆突状物体的顶点，较为正式；top 是最通用、最口语化的说法，几乎可指任何物体的顶部；peak 特指山峰一类尖锐突起的顶点，也常用于比喻意义；crest 多指山丘、山脊或波浪的顶端。这里不比较 crown 的“王冠”义、top 的“陀螺”义、peak 表示（数值）峰值的引申义，以及 crest 的“羽冠”义。
