The document discusses techniques for writing coherent paragraphs and connecting ideas. It begins by defining coherence and explaining that transitional words and phrases establish relationships between sentences by indicating time, spatial, or sequential order. Six categories of transitional elements are described: spatial order, time order, numerical order, cause/effect order, comparison/contrast order, and general/specific order. The document emphasizes that paragraphs need transitional elements to be understandable and coherent, with all sentences arranged in a clear, logical order. It provides examples of transitional words and phrases for different categories.
