<注釋>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 Latinpôtiô, 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 pôtiôn- ) 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 300.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 200.
Poison potion 這一詞組除了押頭韻外還是由同源異形詞構成的， 也就是兩詞最終可歸結到另一種語言中的同一本源。這兩個詞的來源都是拉丁詞potio , 意為.喝的行為、一種飲品或一定的液體劑量，如藥或毒藥。.我們今天所使用的potion 保留了這一拉丁詞的形式（實際上是詞干 potion- 的形式）和.藥劑.的意思， 雖然它是經(jīng)由古法語（pocion ）傳入中古英語的（ pocion ）， 該中古英語記錄最早見于300年左右著成的一部著作中。在古法語中pocion 是一個學術性的借詞， 該詞是以一種和其拉丁文形式對應的形式主動從拉丁文中借用的。但這一拉丁詞也已經(jīng)以另一種形式通過俗拉丁語，即poison ，傳入古法語。 這個詞意為.飲料、..液體劑量.以及.毒性的飲料、毒藥。.Poison 這個詞最早是在一部大約在200年寫成的著作中記進中古英語的。
