"Let's hang out in Seoul tomorrow!"

Translation: 내일 서울에서 놀아요!

[SabianF]

Tell me why 만납시다 can't meant "Let's hang out"? Reported.

[Druckles]

It means meet, not hang out. It just refers to the action. You could meet in Seoul and hang out in Busan.

[Emma599223]

It's means let's meet

What does the preposition ~서 mean?

[kimmksk]

"에서" is one 'preposition' which refers to "in (the place)"

[nleconte]

Exactly. This is a location particle (not really preposition as it comes after the noun, not before).

The choice between 에 versus 에서 depends on the verb that follows. Action verbs (like this one) require 에서, "movement" (don't remember the exact terminology) verbs, like 가다, 오다, etc, require 에.

Is "hang out" the best translation?
