Chingu (친구)

namja = man
gyo ja = female
여자 = female
여자친구? a girl friend ; but could be also just female friend
to be absolutely a "girl friend" better just use 애인 <--can be used for both sex
example : " is he your 애인? " means is he/she your lover or beloved person?
애인 <-- easier... and more like a lover coz 여자친구 <-- can be also just a friend

namja chingu iso? = do you have a bf?
우린 친구 = we are friend = wu rin chin gu
친구 = chin gu = friend
wu ri = we
우린 = wu rin = we are
wu ri chin gu ga? wu rin chin gu ji <-- can be both a asking question and replying question, it depends on what kind of question is the accent of the last word, and it depends on the accent that what kind of question it becomes. aiyooh... quite difficult to express T.T
