Metadiscourse refers to writers' discourse about their discourse—their directions for how readers should read, react to, and evaluate what they have written about the subject matter. In this study the authors divided metadiscourse into textual metadiscourse (text markers and interpretive markers) and interpersonal metadiscourse (hedges, certainty markers, attributors, attitude markers, and commentary). The purpose was to investigate cultural and gender variations in the use of metadiscourse in the United States and Finland by asking whether U.S. and Finnish writers use the same amounts and types and whether gender makes any difference. The analyses revealed that students in both countries used all categories and subcategories, but that there were some cultural and gender differences in the amounts and types used. Finnish students and male students used more metadiscourse than U.S. students and female students. Students in both countries used much more interpersonal than textual metadiscourse with Finnish males using the most and U.S. males the least. The study provides partial evidence for the universality of metadiscourse and suggests the need for more cross-cultural studies of its use and/or more attention to it in teaching composition.
