Why it works
Eliot starts with a rhyming couplet, only to disrupt it with a third line that lacks a rhyme and presents a jarring image. This approach showcases free verse embracing rhyme on its own terms rather than being constrained by it. The poem shifts between rhyme, meter, and refrain at will — all by design. This intentional use of formal elements, as opposed to strict adherence to them, is what free verse allows and what imparts Prufrock its restless, modern anxiety.
