Why is ㅈ realized differently in 맞아요 than ㅊ in 꽃아니요? Similarly, when 꽃 is combined with other suffixes to form a larger, grammatically different word, we can see the ㅊ sound behave in the same way For example; 꽃 + -이 (subjective case marker) = 꽃이 꼬치 꽃 + -을 (objective case marker) = 꽃을 꼬츨
Pronunciation of ㄷ (ㅅ, ㅈ, ㅌ, ㅊ, ㅆ, ㅉ) before ㄱ I can't find information about right pronunciation of patchim ㄷ(ㅅ, ㅆ, ㅈ, ㅉ, ㅌ, ㅊ) before ㄱ From what I can hear ㄷ should be silent But I am not sure about it For example in words like 웃겨 I hear 우껴 and not 욷껴 Similarly 맛있게 for me sounds like 맛이께 and not 맛읻께
