This paper presents an empirical study of repetition in expository essays written by 24 nonnative speakers (NNS) and 16 native speakers (NS) of English. Repetition is coded according to three categories: the degree of particular types of repetition, the interaction between instances of repetition, and the location of these interactions (Hoey, 1991). Four quantitative measures devised for this study show no significant differences between the two groups. A qualitative comparison of three essays from each group, however, shows that the NSSs do not match their degree of repetition to the development of the argument structure of the text in the same way as the NSs. These examples from NNS texts show that when considering the significance of repetition the content of what is being repeated is as important as the quantity.
