Gnerally, when an author halts the flow of a story to comment on something of importance, be it a theme or a motif, or a character, or even a situation that has come up in the story it is known as the segment of commentary.
<u>In this segment the author is talking to the audience directly and not through a character or a story. </u>
<u>The writer is responding to where the story has till now taken the reader.</u> Thus, the narrative is often contextualized from a commentary statement providing new insights and opinions.
