The transitional hook functions as a sentence or phrase that transitions ideas between paragraphs by building a natural sequence in written or spoken text. Such hooks serve as a distinctive signal to guide understanding which signals that change is taking place regardless of whether a new argument emerges or a contrast follows or an example arises or the content builds forward. Gradual bridges maintain consistent flow throughout written works especially in essays along with articles and speeches where they help readers understand successive ideas. After presenting your main point in one paragraph you can begin the following section with "Building on that idea" or "In contrast to the previous point" to establish the connection. A good grasp of the ideas' connection will help you select the appropriate transition to express their relationship.
