窈冥（上𦝫鳥反郭注爾雅窈幽靜也說文深遠也從穴幼聲下莫瓶反毛詩傳云冥夜也說文幽暗也從曰從六謂十六日而月始虧冖聲）。

Obscure and dark (窈冥): The first character is pronounced *yao* + *niao* fan. Guo [Pu's] commentary on the Erya says: '窈 means serene and tranquil.' The Shuowen jiezi says: 'Deep and distant. It is formed with [the semantic classifier] cave (穴) and the phonetic component *you* (幼).' The second character is pronounced *mo* + *ping* fan. The Mao commentary on the Book of Odes says: '冥 means night.' The Shuowen jiezi says: 'Dark and obscure. It is formed from sun (曰) and six (六), referring to the sixteenth day when the moon begins to wane, with the phonetic component *mi* (冖).'
