What literary device is primarily used in describing the whippoorwill’s repetition?

The literary device of repetition is prominently used in describing the whippoorwill's call, as it emphasizes the bird's distinctive sound and creates a rhythmic quality that enhances the overall mood of the passage. This technique helps to evoke a sense of familiarity and highlights the persistent nature of the whippoorwill's call, which can echo through the night, embodying themes of longing or solitude.

This choice captures the essence of how the repeated phrase or sound contributes to the atmosphere of the piece and aids in immersing the reader in the setting. By drawing attention to this particular auditory aspect, the repetition becomes a crucial element in conveying the experience and emotions associated with the scene. Other options, while significant in their own right, do not directly address the core use of repetition in this context.
