Elaboration, or detail, refers to the process of adding more information to enhance understanding. It involves expanding on a main idea by providing examples, explanations, or descriptions that clarify the topic. This technique is commonly used in writing, presentations, and discussions to make concepts more vivid and relatable. In educational settings, elaboration helps students grasp complex subjects by connecting new information to what they already know. For instance, when learning about photosynthesis, a teacher might elaborate by explaining how chlorophyll absorbs sunlight, making the process easier to visualize and comprehend.
