Discourse style refers to how language is used depending on the context, including the subject matter, audience, occasion, and purpose of communication. There are different styles such as public speaking which is carefully planned with exaggerated intonation and rhetorical devices. Another style is addressing an audience where words are chosen carefully in a formal dialogue. More casual styles include conversations between friends, family or colleagues where social barriers are lower and words are less guarded, or intimate conversations where one reveals their inner self.
