What is the theme in Much Ado about Nothing by William Shakespeare?

In Much Ado About Nothing, Shakespeare creates a world entirely of language and shows the dangers and beauties of this world. In the beginning, the verbal sparring between Beatrice and Benedick is the most evident sign of the value of facility with language, and metaphors are used in abundance (often involving animals, further highlighting the importance of language as an element of the most "evolved" species of man). Claudio, indeed, laments that he is not able to woo Hero with his own words, and Don Pedro must take on the task for him. However, though a quick wit and comeback is prized in this society, it is also a weapon that can be used against the protagonists.
