Explanation on grammar in Korean language education should differ from the conventional descriptive grammar or the grammar system of language education. It is necessary to restructure the linguistic expressions in Korean language by focusing on the expressive needs of students while also taking consideration of the agglutinative characteristic of Korean. With the objective to enhance the communicational ability of students in mind, essential linguistic expression items were restructured in terms of such expressions as [hope, speculation, permission, suggestion, intention, tense]. And then teaching methods for Permission Expression item were discussed. This is related with the composition of {-어야 되다/하다} among Korean modalities, which represent [permission, allowance, enforcement, inhibition, wish]. Considering the steps when presenting in Korean language education, presenting in “complementary verb ‘-어야 하다’ of obligation > -으면 되다 > -으면 안 되다 > -어야 되다 > -어도 되다/좋다/괜찮다 > -어서는/어도 안 되다 > -어야지(요) > -지 않으면 안 되다” are proposed.
