| 释义 | 〔poison〕The phrasepoison potion besides being alliterative also consists of doublets, that is, two words that go back ultimately to the same source in another language.The source for both words is Latinpōtiō, which meant "the act of drinking, a drink, or a liquid dose, as of a medicine or poison.”Our wordpotion retains the form of the Latin word (actually the form of the stem pōtiōn- ) and the "dose" sense, although it passed through Old French (pocion ) on its way to Middle English ( pocion ), first recorded in a work composed around 1300.In Old Frenchpocion is a learned borrowing, one that was deliberately taken from Latin in a form corresponding to the Latin form.But the Latin word had also passed through Vulgar Latin into Old French in the different formpoison. This word meant "beverage,” "liquid dose,” and also "poison beverage, poison.”The wordpoison is first recorded in Middle English in a work composed around 1200. Poison potion 这一词组除了押头韵外还是由同源异形词构成的， 也就是两词最终可归结到另一种语言中的同一本源。这两个词的来源都是拉丁词potio , 意为“喝的行为、一种饮品或一定的液体剂量，如药或毒药。”我们今天所使用的potion 保留了这一拉丁词的形式（实际上是词干 potion- 的形式）和“药剂”的意思， 虽然它是经由古法语（pocion ）传入中古英语的（ pocion ）， 该中古英语记录最早见于1300年左右著成的一部著作中。在古法语中pocion 是一个学术性的借词， 该词是以一种和其拉丁文形式对应的形式主动从拉丁文中借用的。但这一拉丁词也已经以另一种形式通过俗拉丁语，即poison ，传入古法语。 这个词意为“饮料、”“液体剂量”以及“毒性的饮料、毒药。”Poison 这个词最早是在一部大约在1200年写成的著作中记进中古英语的。 〔radiotoxic〕the radiotoxic effects of radium on bone.镭对骨骼的放射性毒性作用〔toxicity〕The degree to which a substance is toxic.毒效：一种物质毒性所达到的程度〔batrachotoxin〕A steroid alkaloid derived from skin secretions of thePhyllobates and Dendrobates genera of South American arrow-poison frogs.
