The document discusses language issues in English for Specific Purposes (ESP) approaches. It notes that ESP approaches are sometimes criticized for their perceived lack of focus on grammatical accuracy, but ESP teachers can directly address grammar in the classroom or allow materials and student output to teach it. Grammar is dealt with not as a separate topic, but as a natural part of language use within different contexts. Vocabulary is also addressed in context of the subject matter. Discourse analysis looks at how texts are structured in different genres, and the goal of ESP is to help students identify patterns in their field.
