The 어다 part means going to get something and bringing it here, and 놓다 is putting it down. The verb in front says what kind of fetching: 가져다 놓다 for objects, 데려다 놓다 for people you bring along, 불러다 놓다 for people you summon. One caption plays on the old phrase about a borrowed sack of barley set down in the corner, which describes someone parked in a room with nothing to say.
