What is a clincher sentence?

A clincher sentence is a concluding statement that reinforces the main idea or argument of a paragraph or essay. It is typically the final sentence in a paragraph and serves to leave a lasting impression on the reader. A clincher sentence should summarize the key points discussed in the paragraph and provide closure to the topic being discussed. It may also offer a call to action, provoke further thought, or leave the reader with a strong impression or emotion. A well-crafted clincher sentence can help tie together the ideas presented in a piece of writing and leave a lasting impact on the reader.
