閹豎（上奄炎反下音樹說文云閹即豎也宮中閹閽閉門者今日官人即黃門也形聲字也下豎字說文從豆律從立俗字也閽音昏）。

閹豎 ('court eunuch'): the first character is [pronounced] with the fanqie 奄炎; the second character is pronounced shù. The Shuowen says: '閹 (yān) is precisely a 豎 (servant/eunuch). In the palace, the eunuch doorkeepers who close the gates are today's palace officers, namely the yellow gatekeepers (eunuchs).' It is a phono-semantic character. As for the lower character 豎, the Shuowen says it takes 豆 (vessel) and 聿 (brush); writing it with 立 is a popular variant form. 閽 is pronounced hūn.
