plumbing 的词源

15世纪中期，“钓鱼线的加重”，名词形式来自plumb（动词）。在早期现代英语中意为“铅加工的艺术”。特定意义上指“用于在建筑中输送水的水管、排水管及其他设备”，1875年记录，属于美式英语。

THE apparatus by which the water from a reservoir is carried about over a building and delivered at points convenient for use, is called by the general name of plumbing. The word "plumbing" means lead-work; and it is used to signify this water apparatus of a house because the pipes of which it largely consists are usually made of lead. [Edward Abbott, "Long Look House: A Book for Boys and Girls," Boston, 1877]

从水库输送水并在建筑物中方便使用的装置，统称为plumbing。 “plumbing”一词意为铅加工；它用来指代房屋中的水管设备，因为这些水管大多由铅制成。[爱德华·阿博特，《长望屋：一本男孩和女孩的书》，波士顿，1877年]
