四隅（遇俱反韻詮云屋角也考聲云四角曰隅說文𧿨也從阜禺聲經從山作嵎日出處山名也尚書嵎夷曰暘谷是也）。

四隅 (fanqie: 遇俱. The Yunquan says: 'The corner of a room.' The Kaosheng says: 'The four corners are called 隅.' The Shuowen says: 'A corner.' It is formed from [the semantic component] 阜 and 禺 as the phonetic component. The sūtra writes it with 山 (mountain) as 嵎, which is the name of a mountain where the sun rises; the Shangshu's 'Yuyi is called the Valley of the Rising Sun' refers to this).
