This document discusses discourse markers, which are words like "however" and "although" that are used to connect ideas in writing. It provides a table that lists common types of relationships between ideas (e.g. adding, contrasting, condition) and the discourse markers typically used to express each relationship (e.g. "moreover", "yet", "if"). It notes that discourse markers can be used at the start of sentences or clauses separated by semicolons. The document also discusses how paragraphs are linked together using discourse markers that reinforce, contrast, or concede the ideas in the previous paragraph.
