Why are supporting details crucial in writing?

Supporting details are crucial in writing because they provide evidence and clarification for the main idea. When a writer presents a central concept or argument, supporting details help to strengthen that idea by offering facts, examples, or explanations that illustrate or back it up. This additional information allows readers to understand the main idea more fully and see its significance. Without these details, the main idea may remain vague or unconvincing, making it harder for the reader to understand the author's intent or perspective. In essence, supporting details are vital for clearly conveying thoughts and ensuring the reader can engage with and comprehend the text.
