Sanggung was the highest rank for the court ladies and there were two conditions for a court lady to be appointed as a sanggung: one was through advancement after years of serving in the palace and the other one through special appointment by the queen when she slept with the king. The special sanggung had a higher status compared to the ordinary sanggung since she was the woman favoured by the king, but she’s not yet a royal concubine. The ordinary sanggung acted as supervisors to the other court ladies but they were directly held the responsibility of sanggi and jeoneon.

    I don’t think the young Deok Im understood what it meant to be the highest Sanggung (consort) yet or does she? She could be aiming at being an ordinary sanggung.
    What say you?

      I figured she just meant ordinary Sanggung, at least at this point (or didn’t understand the other meaning), but then after he talk with the King and the other head Court Lady maybe she started to understand a bit more.

        Yes, and based on history being a spoiler, she didn’t seem to want the consort part of it.

          The head court lady (is she the Sanggung (normal)?) seemed almost to be pushing for her to become a consort in that funeral march scene though… or was I reading that scene wrong haha. I was like, goodness, she’s a child, hauld yer wheesht!

            Oh, she sounded like she was totally putting her own ambition on Deok Im’s shoulders.
