Answer: A clincher sentence is defined as a statement, argument, fact, situation, or similar, determining or complete. In academic writing, this is a statement in a descriptive section that repeats the topic and summarizes how the information in the section supports the topic.
While a strong sentence is the last part of the paragraph, we should not bring it to ourselves. So you should not say openly that “this is the end of my story” or “this is the conclusion of my story”
If you want to write an effective paragraph, a clincher sentence at the end is a must. It wraps up the topic, provides closure, and concludes the writing.
