This document discusses what makes a text and the key components of texts. It explains that texts must be self-contained, well-formed, hang together, make sense, and have a clear purpose. Cohesion and coherence are achieved through various linguistic devices like conjunctions, pronouns, and repetition. The context, register, topic, audience and purpose all influence the type of text that is produced. Different types of texts include classroom texts, literary texts, and authentic texts adapted for language learning. Tasks must be designed to work with texts based on factors like vocabulary, grammar complexity, and the intended skill being practiced.
