This document discusses connectives, which are words or phrases that connect ideas in a speech and indicate their relationship. There are four main types of connectives: transitions, which indicate moving to a new idea; internal previews, which preview the next point; internal summaries, which summarize a preceding point; and signposts, which indicate the speaker's current place in the speech or focus on key ideas. The document emphasizes that using connectives effectively makes speeches more unified and coherent.
