The present study aims to investigate the direct and indirect contributions of Korean EFL college students’ L2 receptive and productive vocabulary knowledge to their L2 writing performances by using a structural equation modeling (SEM) analysis with a goal to explore the pathways of vocabulary knowledge to writing. Data from 178 students were collected through tests of receptive and productive vocabulary breadth and depth, a writing test and a reading test. In testing a hypothesized model on the roles of receptive and productive vocabulary in writing, the results of the SEM analysis reveal the direct role of productive vocabulary in writing. The indirect role of receptive vocabulary on writing was observed through the mediating role of productive vocabulary or reading ability due to the direct contribution of receptive vocabulary to both productive vocabulary and reading and that of productive vocabulary and reading to writing. Findings from the study shed light on the relations of L2 receptive and productive vocabulary knowledge with L2 writing abilities, suggesting potential benefits of both receptive and productive vocabulary learning for L2 writing.
