Korea grammar '-는데/-ㄴ데/은데(3)'

1. Explanation

 : '-는데/ㄴ데/은데(3)' is an ending particle which indicates surprise or feeling with speaker's emotion, or is used when waiting for reaction. 

 It conjugates with varrious forms. So, we should check the form of each case. First, when it conjugates with the verb, you can conjugates the verb stems with '-는데'. If the verb stem ends with the final consonant 'ㄹ', you should drop the final consonant 'ㄹ'. Second, if the adjective stem ends with the consonant, you should conjugates the adjective stem with '-은데'. However when adjective stem ends with the vowel or the consonant 'ㄹ', you have to conjugates the adjective stem with '-ㄴ데'. Also fo this way it is used as an ending particle, so you can easily see '-는데요./-ㄴ데요./-은데요.'
