The document discusses the confusion between discourse analysis and text analysis in the literature. Some researchers use the terms interchangeably or propose distinctions that do not hold up. For example, Widdowson proposed that discourse involves coherence while text involves cohesion, but later changed his view. Others proposed text refers to written language and discourse refers to spoken, but models have been applied across modalities. Most researchers now see discourse analysis as studying language beyond the sentence in any form. The document concludes the term "text" should only refer to physical arrangement on paper to avoid confusion.
