In the famous song "muss i denn", I see these two lines(I know it's old German). (ref : https://en.wikipedia.org/wiki/Muss_i_denn)
Denk du net, wenn i 'ne Andre seh', No sei mein' Lieb' vorbei;
Denk du nicht, wenn ich eine Andre sehe, noch sei mein Liebe vorbei
is 'sei' the imperative form of sein? (I guess so). and
vorbei sein is something like
be finished. I can't exactly understand the 'No' part here. How is
No here literally translated? Is it
I think this song is about the true love and commitment of a man to a woman and is very beautiful and touching.
