In writing, what purpose do transitional words serve?

Transitional words play a crucial role in writing by guiding the reader through the text. They help to clarify the relationship between ideas and indicate the flow of thought, making it easier for the reader to follow the argument or narrative. By using transitional words, a writer can show connections such as contrast, addition, cause and effect, and time. This guidance enhances the overall coherence and readability of the material, allowing readers to more effectively understand the progression of ideas.
