for 위해

N + 을/를 위해 V+ 기 위해 It means ‘for(the sake of~)’. While ‘for’ in English has a wide range of meanings, ‘위해’ in Korean is used only to indicate benefit for a particular person or thing. You can use either ‘~위해’ or ‘~위해서’. It's not a marker, still it’s often used after a noun, functioning like a marker.

엄마를 위해서 파티를 열 거예요.

I will hold a party for my mom.

친구를 위해 기도해요.

I pray for my friend.

건강을 위해서 운동을 해요.

I exercise for my health.

• When it's followed by a noun, '~위한' is used.

나라를 위한 희생을 잊지 맙시다.

Let's not forget the sacrifice for our country.

• You can use it with verbs in the form of 'verb root+기 위해(서)'. In this case, it expresses purpose more explicitly and can be translated as “in order to ~.”

엄마 생신을 축하하기 위해서 파티를 열 거예요.

I will hold a party to celebrate my mom’s birthday.

컴퓨터를 배우기 위해서 학원에 다녀요.

I go to an academy in order to learn computer.

(The meaning is similar to the connective ending '으려고', but '-기 위해서' expresses purpose more strongly, while '-으려고' simply indicates intention.)
