This study is to find the possibilities of "Reading grammar", integrating reading and grammar domains in Korean language education. In order to prove this, we established the Reading grammar which is integrating reading and grammar, and then, tried its conceptualization, educational meaning, and case of activity. Current grammar education has been one-sided as the delivery that conveyed the learner``s social meanings and isolated contents. So, grammar education also needed to realize the subject``s social meaning to integrate the language use and grammar. Meanwhile, when we considered the reading and grammar domain as the structure of Korean education, we saw the possibilities that the two domains could be combined, and also found many theoretical basis. Thus, Reading grammar was possible to be established and its concept was dependence grammar about the grammar and reading domains. It could contribute to not only leaners`` reading effect and expansion of grammar knowledge but also the educational importance. In conclusion, providing the characteristics, descriptive ways, content categories, and examples about grammar to identify the real application of Reading grammar, we expect the significant educational effect through this trial.
