well (adv.)

"以令人满意的方式",古英语 wel "丰富,非常,非常多;的确,可以肯定;有充分的理由。几乎,大部分,"来自于原日耳曼语 *wel- (来源也是古撒克逊语 wela ,古北欧语 vel ,古弗里斯兰语 wel ,荷兰语 wel ,古高德语 wela ,德语 wohl ,哥特语 waila "好"),来自于PIE根 *wel- (2)"希望,意愿"(来源也是梵文 prati varam "随意",古教会斯拉夫语 vole "好",威尔士语 gwell "更好",拉丁语 velle "希望,意愿",古英语 willan "希望;"见 will (v.)).

在古英语中也用作插入语和表示惊讶。该形容词在古英语中的意义是"幸运、快乐",来自副词;"令人满意"的意义来自14世纪晚期;"合意的希望或愿望"来自15世纪中叶;"身体健康,不生病"来自1550年代。 Well-to-do "繁荣"到1794年就有记载。

well (v.)

"涌现、上升、涌出",古英语 wiellan (盎格鲁语 wællan ), weallan "沸腾、冒泡、上升(指河流)"的因果关系(七级强动词。过去时 weoll ,过去分词 weallen ),来自于原日耳曼语 *wellanan "滚"(也是古撒克逊语 wallan ,古北欧语 vella ,古弗里斯兰语 walla ,古高德语 wallan ,德语 wallen ,哥特语 wulan "冒泡,沸腾"的来源),来自于PIE根 *wel- (3)"转动,旋转",在"水的沸腾或冒泡"的概念上。"

well (n.)

"挖洞取水,水泉",古英语 wielle (西撒克逊语), welle (盎格鲁语)"水泉、喷泉",出自 wiellan (见 well (五))。"一旦泉水开始被利用为供水源,它就或多或少地彻底变成了一口井"[世纪词典]。形象意义上的"源头,任何东西都是从这里引来的"是古英语。
