Imperialism, according to the Merriam Webster Dictionary, is "the extension or imposition of power, authority, or influence" over another nation. Consequently, linguistic imperialism is the extension or imposition of one's own language over another's. Martin Luther's Bible translation is a good example, Georg Hegel's German Die Philosophie der Weltgeschichte (1830) is another; the former made the Bible German, the latter made world history German. Language imperialism is more surgical than that: It is the translation of foreign key terminologies into familiar vocabulary of one's own language tradition in order to claim deutungshoheit, to diminish another culture's originality, or to pretend to have full comprehension of a foreign topic by simply switching into one's own lingua. So even if a nation is not strong enough to impose its own language over another's, like Germany could never conquer the Chinese people, it could always try to steal important cultural property by giving it German names.
