You can identify imagery by looking for vivid descriptions that appeal to the senses, like sight, sound, smell, taste, and touch. For example, if the author describes a beautiful sunset in detail, that's imagery.
Identifying imagery in a novel involves noticing when the author uses words and phrases to make you feel like you're experiencing what the characters are. It might be descriptions of nature, objects, or emotions that are very sensory-based. Like 'The thunder roared, shaking the windows' or 'Her smile was like a warm summer breeze'.
To spot imagery in a novel, pay attention to the language used. Descriptions that create mental pictures or evoke emotional responses through sensory details are likely imagery. It could be something as simple as 'The cold wind bit my cheeks' or 'The sweet aroma of fresh-baked cookies filled the room'.
