안녕하세요! Welcome to the very first Sentence Building Drill (문장 만들기 연습) lesson! In this series, we will look at how you can expand your Korean sentence building skills by adding or replacing certain words in given sentences. All the “key” sentences that are used in these lessons are composed of grammar points that have previously been introduced through our lessons. This series will be a good opportunity for you to review what you have learned in the past and also to learn some new vocabulary! Have fun studying!
