ether[ether 词源字典]

ether: [17] Greek aithér denoted the ‘upper atmosphere’, and by extension the ‘substance that permeated the cosmos’, from which the stars and planets were made. It was a derivative of the verb aíthein ‘ignite, blaze, shine’, a relative of Latin aestās ‘summer’, from which English gets aestivate [17]. It passed into English via Latin aethēr, and to begin with was used in its original Greek senses. Its application to the liquid with anaesthetic properties dates from the mid 18th century, the use of its first syllable in the names of organic compounds in the bicarbon series (such as ethyl and ethane) from the mid 19th century.
