24.142

屋宇 (The ancient form is 㝢, and the seal script form is 𢉠, both with the fanqie 于甫 [y- + -ǔ = yǔ]. The Shuowen jiezi says: '宇 means the eaves of a house.' The Shiming says: '宇 means feather (羽), like a bird's feathers covering and sheltering itself.' The Zuozhuan says: 'Lost its 宇.' The commentary states: 'Regarding a state, the four overhangs are the 宇. 宇 also refers to the eaves of a house, or a dwelling').
