Korean Grammar Made Simple

Ronald D Wilder is a language educator and materials developer with over fifteen years of experience teaching Korean to English-speaking learners. He began studying Korean in 2005 during a two-year residency in Seoul, where he discovered both a deep appreciation for the language and a frustration with the available self-study materials—most textbooks were either overly academic or designed for classroom use with a teacher. This experience led him to develop his own approach: grammar instruction that prioritizes active production through exercises over passive reading of rules.

Wilder holds a Master's degree in Applied Linguistics from the University of California, Los Angeles, where his research focused on second-language acquisition of morphosyntactic systems, particularly the acquisition of Korean particles and honorifics by English-speaking learners. He has presented at the annual conference of the American Association of Teachers of Korean (AATK) on topics including the design of self-study grammar curricula and the role of contrastive analysis in teaching Korean verb endings to English speakers.

Before focusing on Korean, Wilder taught English as a second language to university students in Japan and South Korea, giving him a broad perspective on the challenges learners face when moving between structurally different languages. He is the author of several language learning resources, including *Japanese Verb Conjugation Workbook* and *Chinese Measure Words: A Practical Guide*, both of which follow the same exercise-heavy, self-study methodology used in this book.

Wilder currently lives in Portland, Oregon, where he develops online Korean courses and writes about language learning. He maintains that the most important quality for a language learner is not talent but persistence—and that a well-designed set of exercises can make persistence productive.
