A Corpus-Based Study of Korean EFL Learners’ Use of Subordinate Conjunctions in Argumentative Writing: With Focus on if, when, and because

Abstract

The use of subordinating conjunctions in L2 writing has been widely studied with regard to frequency of occurrence, grammatical accuracy, and relative ordering of subordinate and main clauses. However, relatively few studies investigated the diverse aspects of the L2 use of subordinating conjunctions within a single study. The present study analyzed three representative subordinating conjunctions, if, when, and because as used in a proficiency-stratified Korean EFL written corpus in terms of their frequency of occurrence, grammatical accuracy, and linear ordering relative to the main clause. The results revealed that the proficiency effect on frequency and grammatical accuracy varied among the three subordinating conjunctions, whereas that on linear ordering of subordinate clauses was uniform across conjunctions. The findings provide implications for a better understanding of L2 adverbial subordinate clauses and its application to teaching practice.
