This book, Understanding L2 Korean Learner Errors, deals with errors made by learners of Korean as a second or foreign language at three levels: orthography, lexicon and grammar. This book identifies and describes a variety of high frequency error types and explains the causes of the errors. It further investigates sources that cause errors by employing descriptive, contrastive, psycholinguistic theories and techniques while dealing with pedagogical implications and presenting focused instructional strategies for selected key error types. Laying out the basics for any understanding of error analysis as well as presenting important topics around high frequency error types and a survey of error analysis undertaken in Korean, Understanding L2 Korean Learner Errors is an ideal resource for researchers and postgraduate students who are working on the analysis of Korean language learners’ errors. This book is an insightful reference for anyone who is interested in the teaching and learning of the Korean language.
