"더 or 또 you can say du or ddo" in Korean an additional thing or person of the same type as one that already exists. "Would you like another drink?" = 음료수 한 잔 더 할래? For example I am drinking a bottle of beer and I almost drank all. so a friend of mine recommend one more drink. I am not sure it is helpful for you . But I did my best to explain....haha thanks
