다 드리다

fetch it and bring it to you (polite)

-어다(가) means doing something in one place and moving elsewhere to complete it, and 드리다 is the humble 'give' used toward the person you are serving. 갖다 드리다 'go get it and bring it to you' dominates here: 형 콩나물국밥 좀 갖다드릴까? 'shall I bring you some soup?'. Also present are 사다 드리다 'buy it and bring it to you' and 바래다 드리다 'see you home'. The plain-speech version is -어다 주다.

Register: polite; offering to serve someone
