는데 Grammar is tricky Hello :) , i hit really tricky grammar, which is '는데' . I checked my grammar book and some free resources like TTMIK and i got certain view, but... it's tricky. It's really easy to interchange 는데 with 그래서 and 그런데.( because of the usages and meanings ). I was told that it sounds unnatural. Please, can anyone make little review or explain in different way ? ( Maybe it's just matter of time, i feel that explanation provided by TTMIK is really good, same goes for Korean Grammar in Use, but i am still kinda confused about it. ) Thank you :) with regards John
