contaminateyoudaoicibaDictYouDict[contaminate 词源字典]
contaminate: [15] Contaminate appears to come from the same ultimate source as contact, a base *tag- ‘touch’, which produced the Latin verb tangere ‘touch’ (whence English tactile, tangent, and tangible). It seems also to have formed the basis of a compound Latin noun *contagmen ‘contact, pollution’, which became altered to contāmen. From this was derived the verb contamināre, whose past participle gave English contaminate.
=> contact, tactile, tangible[contaminate etymology, contaminate origin, 英语词源]
staminayoudaoicibaDictYouDict
stamina: [17] Etymologically, stamina is the plural of stamen ‘male reproductive part of a flower’ [17]. The ultimate source of both is Latin stāmen ‘thread of woven cloth’, which went back to Indo-European *stāmen-, a derivative of the base *stā- ‘stand’ (source also of English stand). The application to the plant-part appears to go back to the Roman naturalist Pliny, who used stāmen for the stamens of a sort of lily, which resembled threads of cloth. The Latin plural stāmina was borrowed into English in the metaphorical sense ‘threads of human life, vital capacities’, and by the 18th century it had broadened out to ‘vigour’.
=> stamen, stand
vitaminyoudaoicibaDictYouDict
vitamin: [20] Vitamins were originally vitamines: the Polish-born biochemist Casimir Funk who introduced them to the world in 1920 believed that they were amino acids and so formed the name from Latin vita ‘life’ and amine. It was soon discovered that Funk’s belief was mistaken, and alternative names were suggested, but in 1920 it was successfully proposed (by J.C. Drummond) that the -e be dropped to avoid confusion, and the form vitamin was born.
=> amine, vital

MesopotamiayoudaoicibaDictYouDict

In 19c. the word sometimes was used in the sense of "anything which gives irrational or inexplicable comfort to the hearer," based on the story of the old woman who told her pastor that she "found great support in that comfortable word Mesopotamia" ["Brewer's Dictionary of Phrase & Fable," 1870].
