This document discusses formal and contextual links in language. It describes several cohesive devices that create formal links between sentences:
1. Verb form
2. Parallelism
3. Referring expressions
4. Repetition and lexical chains
5. Substitution
6. Ellipsis
7. Conjunction
It provides examples of each device and explains how they suggest connections between sentences. However, the document also notes that formal links alone are not enough to create coherence - contextual understanding is also required. Language must be understood in terms of its intended functions and the cultural norms of communication.
