Halliday and Hasan's Cohesion Theory

Halliday and Hasan's Cohesion Theory explains how different parts of a text are connected to create clarity and flow. It identifies various linguistic tools, such as referencing (using words like "he" or "this" to link ideas), conjunctions (like "and" or "but" to connect clauses), and lexical ties (repeating or related words). These devices help readers understand relationships between ideas, maintain the coherence of a text, and follow the writer’s message smoothly. Essentially, the theory shows how language elements work together to make written communication logical and easy to follow.
