Step-by-step explanation:
A metaphor is a figure of speech that compares two unlike things without using the words 'like' or 'as'. In literature, metaphors are used to create vivid imagery and enhance the reader's understanding of a concept or theme. An example of a metaphor in a chapter could be 'Her heart was a stone, cold and unyielding.' This metaphor compares the character's heart to a stone, highlighting her emotional distance and lack of compassion.
The effect of this metaphor on the reader is to evoke a strong visual and emotional response. It helps the reader to better understand the character's personality and creates a memorable image in their mind. Metaphors can also add depth and complexity to the writing, allowing the reader to make connections between different elements of the story.
