Which of the following best describes the purpose of transition words?

Transition words play a crucial role in enhancing the flow of writing by clarifying relationships between ideas. They serve as linguistic signposts that guide readers through the text, making it easier to follow the author's logic and the structure of the argument being presented. By indicating connections such as addition, contrast, cause and effect, or sequence, transition words help establish coherence and cohesion within a piece of writing. This clarity allows readers to better understand how different points relate to one another, ultimately enhancing comprehension.

The other choices do not accurately reflect the function of transition words. For instance, listing examples without context fails to provide the necessary connections between those examples, while confusing the reader with complex structures opposes the purpose of transitions, which is to simplify understanding. Lastly, eliminating the need for complete sentences is not the role of transition words; rather, they complement complete sentences to improve overall readability.
