What does coherence in a paragraph help to achieve?

Coherence in a paragraph refers to the logical flow and connectivity of ideas, which is essential for effective communication. When a paragraph exhibits coherence, it means that the sentences and ideas are arranged in a structured manner, allowing the reader to easily follow the writer's thought process. This organization helps in presenting a clear understanding of the main point being conveyed. Each sentence builds on or relates to the previous one, thereby reinforcing the central idea and making it easier for the reader to grasp the intended message. Coherence is crucial for ensuring that the reader does not become lost or confused, which is why it is fundamental to clear writing.
