Final answer:
Uncle Venner describes Phoebe's departure as a bird flying away from its nest in 'The House of the Seven Gables' by Nathaniel Hawthorne.
Step-by-step explanation:
In Nathaniel Hawthorne's The House of the Seven Gables, Uncle Venner uses the analogy of a bird flying away from its nest to describe Phoebe's departure. This imagery of Phoebe spreading her brown wings for flight and soaring into the air emphasizes her natural grace and the transient nature of her stay with her relatives.
The comparison to a bird also suggests a sense of freedom and the start of a new journey, which aligns with Phoebe's character development and her role within the novel.
