language

The character relationship in "The Tempest" that is the best example of linguistic imperialism is:

D. Prospero and Caliban, because one forces the other to speak his  language.

Explanation:

Linguistic imperialism can be defined as the imposition of one language on speakers of other languages. As we know, linguistic imperialism was a weapon of colonization. Colonizers would forbid natives from speaking in their own mother tongues, forcing them to learn the colonizers' language. This was one of the many ways to keep natives under control while depriving them from their original identity and culture.

That type of relationship is seen in "The Tempest", a play by Shakespeare, set in an island ruled by former Duke of Milan, Prospero. Prospero has forced a native islander, Caliban, to learn his language. Just like what happens in real life, Caliban is often called a monster. It is typical of colonizers to try and represent the natives as animals or, at least, as inferior in reasoning and knowledge. However, Caliban is actually perfectly capable of expressing himself and of understanding others. His representation is made through the eyes of the dominant culture, that is, in a prejudiced manner.

the third paragraph is your answer,

"but, in a larger sense, we can not dedicate — we can not consecrate — we can not hallow — this ground. the brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. the world will little note, nor long remember what we say here, but it can never forget what they did here. it is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. it is rather for us to be here dedicated to the great task remaining before us— that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion—that we here highly resolve that these dead shall not have died in vain—that this nation, under god, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth.
