The Middle English wordjonk, ancestor of junk, originally had a very specific meaning restricted to nautical terminology.First recorded in 1353,the word meant "an old cable or rope.”On a sailing ship it made little sense to throw away useful materialsince considerable time might pass before one could get new supplies.Old cable was used in a variety of ways,for example, to make fenders,that is, material hung over the side of the ship to protect it from scraping other ships or wharves.Junk came to refer to this old cable as well. The big leap in meaning taken by the word seems to have occurred whenjunk was applied to discarded but useful material in general. This extension may also have taken place in a nautical context,for the earliest, more generalized use ofjunk is found in the compound junk shop, referring to a store where old materials from ships were sold.Junk has gone on to mean useless waste as well. Junk 一词是被称为词义扩大化的例子；由于世界上垃圾的数量正在迅速扩散和激增，该词词义的扩大也是很适宜的。 junk 一词源自古英语单词 jonk ， 其最初的意思只限于航海术语当中。1353年首次记载下来时，该词义为“旧缆绳或旧绳子”。在帆船上，扔掉有用的东西是不明智的，因为也许要过去好长一段时间才有可能得到新的供应品。旧缆绳可用在很多不同的方面，例如用来做防撞物，即悬在船舷上保护船舷不受其它船只或码头刮擦的材料。Junk 同样也用来指旧缆绳。 当junk 普遍地被用来指丢弃了的然而有用的材料时，该词的词义发生了巨大的变化。 该词的词义延伸也可能已经出现在与航海有关的背景中，因为junk 一词最早的、更为概括性的使用是在 junk shop 这一复合词中发现的。 该词指出售船上旧材料的商店。Junk 仍继续用来指没用的废旧物品 〔penetrate〕To cause to be permeated or diffused; steep.浸，泡：使被渗透或扩散；湿透〔diffusion〕The process of diffusing or the condition of being diffused.扩散：扩散的过程或扩散的条件〔overrun〕To spread or swarm over destructively:散步，蔓延：破坏性地扩散或群集于…上方：〔contagion〕The tendency to spread, as of a doctrine, influence, or emotional state.感染力：蔓延扩散的倾向，如学说、影响或情绪等〔gas〕The state of matter distinguished from the solid and liquid states by relatively low density and viscosity, relatively great expansion and contraction with changes in pressure and temperature, the ability to diffuse readily, and the spontaneous tendency to become distributed uniformly throughout any container.气态：一种区别于固体和液体的物体状态，有相对较低的密度和粘度，相对较高的随气压和温度改变的扩展度和收缩性，易于扩散，在任何一个容器内均匀扩散〔lather〕To spread with or as if with lather.以泡沫覆盖：通过或好象是通过肥皂泡来扩散〔swell〕To rise or extend above the surrounding level, as clouds.升起，扩散：象云一般从四周水平面上升或扩展〔nonproliferation〕a nonproliferation treaty.防止（核武器）扩散条约〔myelofibrosis〕Proliferation of fibroblastic cells in bone marrow, causing anemia and sometimes enlargement of the spleen and liver.骨髓纤维化，骨髓纤维变性：在骨髓中成纤维细胞的扩散，常引起贫血症，而且有时也会导致脾和肝的增大〔nonproliferation〕Of, relating to, or calling for an end to the acquisition of nuclear weapons by additional nations:防止（核武器）扩散的：属于、关于或为防止被其它国家获得核武器而召集的：〔paraneoplastic〕Of or relating to a syndrome or other systemic disturbance associated with but not directly related to a primary tumor or its metastases.肿瘤伴随的：与主要肿瘤及其扩散部位关联但并非直接关联的症状或其他系统紊乱的，或与其相关的〔mushroom〕To swell or spread out into a shape similar to a mushroom.呈菌状扩散：膨胀或者伸展成象蘑菇的形状〔bleed〕To run together or be diffused, as dyes in wet cloth.扩散：渗开或散开，如湿布上的染料 |
