Answer: The title of Nectar in a Sieve is an allusion to another literary work.
Explanation: Nectar in a Sieve is a novel written by Kamala Markandaya. The author took the title of the book from a poem written by Samuel Taylor Coleridge called "Work Without Hope", which was published more than 100 years before Nectar in a Sieve. Markandaya also includes an excerpt from "Work Without Hope" in the epigraph of the novel. Therefore, it can be said that Markandaya was highly inspired by Coleridge's poem at the time of writing this novel.
