The word choice and tone are the primary aspects of a written work which can help the reader determine the author's purpose. For example, a satire using caustic words will allow the reader to see that the work is a satire and is aimed at being critical of the subject at hand. On the other hand, a humorous work will have a lighthearted tone in which the author uses funny words to describe a situation or a person.
