Choe, Mun-Hong. (2022). A case study of Korean EFL learners interlanguage in verb morphology. The Linguistic Association of Korea Journal, 30(1), 133-155. This study investigated a Korean childs interim knowledge and use of English verb inflections in the context where acquisition is based mostly on written input with limited opportunities for oral production and interaction. The emergence and development of the childs interlanguage were closely examined by analyzing the occurrences and frequency changes of (non-)finite verb forms and their appropriateness in context. Data were collected for about a year from the childs uninstructed spontaneous compositions and analyzed across four time periods. Error classification systems were developed to classify accurate, inaccurate, and formally accurate but functionally inappropriate forms. Overall, the findings indicate that errors in the childs developing language are restricted to only a few types which are also observed in English L1 acquisition, and that the childs L1 does not mediate her acquisition of L2 morphosyntactic features to a significant degree. These seem to imply that child acquisition of L2 grammaticality is driven by sufficient input even when it lacks the qualities of social scaffolding and interactive communication.
