The present study investigates Korean university EFL students’ use of conjunctive adverbials (CAs) in argumentative writing. The data for the study consist of a Korean university students’ writing corpus that is divided into three different subcorpora based on proficiency levels, and a reference corpus of American students’ writings. The results show that the nonnative writers in all three groups greatly overused CAs. Examination of their overuse patterns according to different taxonomic types indicated that sequential and additive types were mostly overused, as much as six times more than those by the native writers. In addition, several characteristics of the nonnative writers’ CA usage are discussed, including their heavy dependence on sentence-initial positioning, and both form-related and usage-related misuses of CAs, especially among the lowest-level learners. The study concludes with some pedagogical implications and suggestions.
