Thanks for your question. Nissim Ezekiel’s poem, ‘Goodbye Party For Miss Pushpa T.S.’ is on the surface a very simple work. But, as you noted, there is something else going on. When one takes the time to exam the ungrammatical sentence structure, the misplaced words and halting language it becomes clear that the poet made a conscious choice to emphasize a specific manner of speech. In this case, what is known as Indian English.
While reading the text a reader is meant to find these moments slightly humorous and as they build on top of one another, more amusing. It was Ezekiel’s intention to very lightly point out, and poke fun at those who are not quite fluent in English.
Within the poem, the speaker does not make use of conjunctions and there are small mistakes such as saying “cooking nicely” or “with men also and ladies also.”
Hope this helps!
