唯然（維癸反案唯者謂譍尊者命亟敬之辭也禮記父召無諾先生召無諾唯而起鄭玄曰唯恭於諾說文唯即諾也從口隹聲）。

Yes, indeed (唯然: [唯 has] the fanqie wei + gui; examining 唯, it is an expression of prompt respect in responding to the command of an elder; the Liji says: 'When one's father summons, do not answer "nuo"; when one's teacher summons, do not answer "nuo"; respond "wei" and rise'; Zheng Xuan says: '"Wei" is more reverent than "nuo"'; the Shuowen jiezi says: '"Wei" is indeed "nuo"; it takes its classifier from 口 "mouth" with 隹 as phonetic').
