Final answer:
The quote uses repetition as a form of figurative language to emphasize inevitability and certainty, and it could also represent an epiphany regarding the conclusion of events.
Step-by-step explanation:
The quote "But it sufficeth that the day will end, and then the end is known" utilizes a form of figurative language that is somewhat abstract, as it does not fit neatly into the categories of simile, metaphor, or imagery. Instead, it uses repetition and plays on the word "end" for effect. The repetition emphasizes the inevitability and the certainty of the outcome, which could also be seen as an epiphany for the character or the narrator. Figurative language can often be open to interpretation and may carry multiple layers of meaning, depending in part on the context within which it is used.
It is important to consider the wider context of the quote when analyzing its figurative language. The statement may hold metaphorical significance within the narrative, suggesting themes of fate, finality, or the nature of time. Without additional context, however, providing a definitive answer is challenging.
