AP [AP 词源字典]: abbreviation of Associated Press, first recorded 1879; the organization was founded May 1848 as co-operative news gathering effort among New York City newspaper publishers covering the war with Mexico.[AP etymology, AP origin, 英语词源]
cooperative (adj.): also co-operative, c. 1600, from Late Latin cooperat-, past participle stem of cooperari (see cooperation) + -ive. Political economy sense is from 1808, from the pre-Marx communist movement. The noun meaning "a cooperative store" is from 1883; meaning "a cooperative society" is from 1921.
nuanced (adj.): 1896, past participle adjective from verb nuance (q.v.).
The new co-operative history of English literature which the University of Cambridge is now publishing prints "genre" without italics. And it even permits one contributor--and a contributor who is discussing Shakespeare!--to say that something is delicately "nuanced." Is there now an English verb "to nuance"? It is terrible to think of the bad language the scholars of the venerable English university might have used if "nuanced" had been first discovered in the text of an American author. [Scribner's Magazine," January 1911]
