This book addresses errors frequently made by learners of Korean as a second or foreign language from three aspects: vocabulary, spelling, and grammar.
The beginning and development of error research in foreign language education and the error research in Korean language education were examined.
In addition, the advantages and disadvantages of error research were outlined, and the educational implications of error research were described by examining the procedures and steps of error research, such as collecting error data, describing errors, and explaining the causes of errors.

Regarding the methodology of error research, the necessity of a qualitative approach for error analysis and classification and a statistical quantitative research method for measuring error frequency and error rate were discussed.
In addition, the most important step in error research was to discuss the types and sources of errors, and the necessity and tasks of corrective education were presented as a way to deal with learners' errors.


We briefly summarize the research on Korean language errors that has been conducted so far, and describe, explain, and discuss some important and common findings regarding high-frequency Korean grammar, vocabulary, and spelling errors frequently made by English-speaking learners.

This book is written in English and provides a Korean summary along with an English index for a wider readership, including undergraduate and graduate students, and established researchers in Korea and abroad who are studying the acquisition, learning, and teaching of the Korean language.


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.
