revolution是个多义词，有小学文化程度的都应该明白“多义词”，只有文盲会觉得是“七拐八弯”。


这个词可用于政权变动。在这方面的英文词典定义如下。

美国韦氏：
a fundamental change in political organization
especially : the overthrow or renunciation of one government or ruler and the substitution of another by the governed

英国牛津：
an attempt, by a large number of people, to change the government of a country, especially by violent action

很简单。
