V-고 나서 grammar = and then, after doing ~express sequential events

L1.21 V-고 나서 grammar = and then, after doing ~express sequential events

Usage:

- Express sequential events that the 2nd event occurs after the completion of the 1st one. = and then, after doing

- In some cases, -나서 can be omitted without changing the meaning. The inclusion of -나서 simply clarifies that the 1st event has completed. 

E.g. 
일하고 나서 쉬세요 = 일하고 쉬세요.
Please take a rest after finishing work

- If the subject of the motion and state verbs are the same in the both clauses,

E.g.
가다 = to go 
오다 = to come
올라가다 = to go up
내려가다 = to go down
일어나다 = to wake up
앉다 = to sit
눕다 = to lie down 
만나다 = to meet

then -아/어서 is used instead of -고 and -고 나서. (See example 5 and 6)
