1. Form verb stem + 어 주다 하다 --> 해 주다 (exceptional conjugation of 하다 verb) 2. Meaning : -어 주다 adds the meaning of helping others by doing something. e.g. 사랑하다 (to love someone or something) VS 사랑해 주다 (to help someone by loving him/her) 3. Sample sentences e.g. 말해 주세요. (Please help me by telling it. = Please tell me!) e.g. 도와 주세요. (Please help me!) 4. 사랑해 주는 사람 VS 사랑하는 사람 4.1. 내가 사랑해 주는 사람 (the person that I help by loving him/her) 4.2 . 내가 사랑하는 사람 (the person that I love) - 내가 사랑해 주는 사람 sounds unnatural. It sounds like the person who is loved does not deserve to be loved. It sounds like you pity on someone and not truly love him/her. It is not a common expression for love.
