Here are the answers as to why an author includes dialect in a story: to allude to a character’s regional background; to allude to a character’s social background; and <span>to add to the cultural context of a story’s setting. When we say dialect, this is the specific form of language that is used by someone who is from a specific region. In other words, this is called as a local language or vernacular. When this is added in a story, this gives it a more culturally specific form of approach. </span>
Answer:
Authors choice of words give a emotional effect to the reader.
Explanation:
Remember that diction is the authors choice of words or phrases he/she uses in a story. In this case the author using certain words and phrases can give a emotional effect to the reader because if you use terms that are serious it will give off a serious tone but if you are trying to come off as serious but using terms or phrases that don't go with that tone you are trying to give off, it might give the reader a different emotional effect that you weren't trying to give.
Hope this helps.
