The phrase “Rest in the bottom lay” uses a pun as the figure of speech. A pun involves a play on words where a word has multiple meanings or similar sounding words are used for a humorous or rhetorical effect. In this case, the word “rest” has two meanings:
- “Rest” refers to what remains or is left over.
- “Rest” also means to relax or find peace.
The phrase “Rest in the bottom lay” thus plays on these two meanings, creating a pun by using the word “rest” to imply both the remaining portion and the act of resting .
