Coherence refers to the logical and consistent connection of ideas within a text or speech. It ensures that the information flows smoothly, making it easier for the reader or listener to understand the main message. Coherence is achieved through the use of clear transitions, relevant examples, and a structured organization of thoughts. In writing, coherence is essential for effective communication. It helps to maintain the reader's attention and enhances comprehension. Techniques such as topic sentences, transitional phrases, and paragraph structure contribute to creating a coherent piece, allowing the audience to follow the argument or narrative without confusion.
