Answer:
I. It develops precise images in the mind.
II. It affects the narrator’s tone in a piece of writing.
Step-by-step explanation:
Diction is the word choice that a narrator or writer of any literary work may use in his/ her work. In speaking, it is easily detectable the tone of the speaker. But in cases of written words that is to be read or being read, the tone of the writer isn't easy to find. As they are not literally spoken out, it is on the reader to try to understand the tone of the words. So, this is when diction comes. Diction is the words that determine what tone the story has and how it is being told.
Suppose, if a writer writes-
"I had my dinner",
it is just plain admission of him about his dinner. But, if that same sentence can be written as-
"I had a plate of glistening barbecued turkey with some fresh green salads and vegetables",
it creates a more pleasing and appetizing picture in the minds of the reader. Then again, if the sentence becomes-
"I had a cold and flaky chicken with overcooked and scorched vegetables for my dinner",
it creates a bad image of the dinner. So, just like the three sentences are the same in their topic of dinner but differ in their descriptions, diction also helps make the image in our minds. Thus, it can be said that diction is important as it develops precise images in the minds. It also affects the narrator's tone in a piece of writing.
