I am familiar with 뭐 as a question word, but what does it mean to end a sentence with it?

I am familiar with 뭐 as a question word, but what does it mean to end a sentence with it?

It kind of just means “I’ve got nothing else to say about it”

You’ll often see “할 수 없지 뭐”

It’s a pretty casual thing to say, but honestly don’t worry about it. You kind of just get the sense when you bump into it enough through videos or speech. Unless you’ve got some pretty close Korean friends, you’re unlucky to really hear it from someone that you talk to. Most likely you’ll get the sense from tv shows where they overplay the emotion that goes along with it :smiley:

Thanks for your response — this is really helpful!!
