Vocabulary is set of words. Therefore vocabulary can be dealt with word study. Word study can be divided into morphology and lexis. So in view of school grammar that deal with phoneme, word, sentence, discourse, and meaning, vocabulary education can be dealt with part of grammar education. Of course vocabulary can be treated in speaking, listening, reading, writing, and literature. Generally speaking, vocabulary study are divided into relation study, distribution study, policy study, grammar education deal with only distribution study. In other words, vocabulary measuring, system and aspect of vocabulary are treated in grammar education. Relation study is treated in semantics, policy study is rarely treated in education. Frankly vocabulary education is treated in elementary school, rarely in secondary school. Only system of native language, sino-korean, and loanword and aspects of local dialect, proverb, idiom etc. are treated in text books. Of course there are no technical teaching methods. And it is reported that paper test is only method in grammar education and there’re no special methods. I think that unified methods in teaching vocabulary and measuring vocabulary competence are possible in grammar education eventually.
