it should be four pages long (not counting tables, examples, figures, references, etc.—those are all free). Where appropriate, use italics to indicate mention qua word and single quotes to indicate mention qua meaning. To answer the question, you may (should) consult any sources you like, but cite your sources in the text and include full references at the end; plagiarism will not be tolerated. Be specific, use examples to illustrate your points, and provide evidence to support your points.
Imagine that you have been sent to the newly discovered planet of Utaboopia that is inhabited by a population of humans. After learning how to communicate with them you find that they do not have any type of taboo language within their culture. Write a scientific article for the Utaboopians explaining what taboo language is, how it functions, and why it exists in Earth culture. Hypothesize about why Utaboopians lack taboo language and what it means for their culture; propose future research to test your hypothesis.
