| 释义 | 〔penthouse〕The wordpenthouse and the structure it denotes have both come a long way. The word goes back to Latinappendere, "to cause to be suspended.”In Medieval Latinappendere developed the sense "to belong, depend,” a sense that passed intoapendre, the Old French development ofappendere. Fromapent, the past participle of apendre, came the derivative apentiz, "low building behind or beside a house,” and the Anglo-Norman plural form pentiz. The form without thea- was then borrowed into Middle English, giving uspentis (first recorded about 1300), which was applied to sheds or lean-tos added on to buildings.Because these structures often had sloping roofs,the word was connected with the French wordpente, "slope,” and the second part of the word changed tohouse, which could mean simply "a building for human use.”The use of the term with reference to fancy penthouse apartments developed from the application of the word to a structure built on the roof to cover such things as a stairway or an elevator shaft.Penthouse then came to mean an apartment built on a rooftop and finally the top floor of an apartment building.单词penthouse 及其所代表的结构都经过了长期的演变。 此词可追溯至拉丁语appendere ， 意为“使悬浮”。在中世纪拉丁语中，appendere 的意思演变为“附属，依靠”， 是词形变为apendre 的意义， 由古法语appendere 发展而来。 从apendre 的过去分词 apent 产生出意为“房屋旁边或后面低矮的建筑”的派生词 apentiz 及盎格鲁-诺尔曼复数形式 pentiz 。 没有a- 的形式被借用到中世纪英语， 变成pentis （首次记载于1300年）， 用作加在建筑上的小棚或单倾斜面的小屋。因为这些结构常有斜屋顶，因此该词与法语词pente “斜面”有关， 且此词的第二部分变成house ， 只简单地意为“住人的建筑”。该词与使人想象楼顶房屋有关的使用源自需要用一个词来表示建在屋顶上用来遮挡楼梯或电梯通道的建筑。Penthouse 于是逐渐意为建在屋顶上的房间， 最终意为一个公寓楼的顶层〔levigate〕To suspend in a liquid.使悬浮在液体中〔float〕To cause to remain suspended without sinking or falling.使悬浮：使保持悬浮而不沉下或跌下〔hang〕To fasten from above with no support from below; suspend.悬吊：固定在上面，下面没有支撑；使悬浮〔centrifuge〕An apparatus consisting essentially of a compartment spun about a central axis to separate contained materials of different specific gravities, or to separate colloidal particles suspended in a liquid.离心机：一种主要包含有一个围绕中心轴旋转的隔间的器械，用于把具有不同重量的物质分离开或使悬浮在液体里的胶质微粒分开 |
