I listen the same song by 2 different singers and one time I hear ” v+고십어” and the other one it ’s “v+고 십은”
I don’t know what 은 is here
I’ve also seen in an other lyric :
v+고십겠지 ( is 지 the négation ? )
and v+고십시만 …
are all this different endings some conjugaison verb or grammatical rule or something else ????
i've tried to find the answer, but i didn't see anything about that.. .
