An extended analogy is a literary device that compares two unlike things in multiple ways over a longer passage or throughout an entire work. Unlike a simple analogy, which makes a single comparison, an extended analogy delves deeper, exploring the relationship between the two subjects more comprehensively.
For example, if we compare life to a journey, an extended analogy might elaborate on various stages of life, such as childhood as the beginning of the journey, adolescence as navigating unfamiliar roads, and adulthood as reaching a destination. Each stage may involve different experiences, challenges, and lessons, drawing parallels to the various phases of a journey.
Writers often use extended analogies to clarify ideas, enhance themes, or evoke emotions. By elaborating on the comparison, readers can gain a deeper understanding of the concept being discussed.
