6.75

Investigate and examine (推究: the first is pronounced with the fanqie 出佳 [chuī]. The Kaosheng says: "To probe and interrogate." The Shuowen says: "To investigate thoroughly; deriving from 'hand' [手] with 隹 as phonetic; it also borrows the character 偕." The second is pronounced with the fanqie 鳩宥 [jiù]. The Mao Commentary on the Classic of Poetry says: "Jiu means deep." The Shuowen says: "Exhaustive; deriving from 'cave' [穴] with 九 as phonetic." It is also written as 𠃙, 𡧫, 𠬚, or [究/敢], all of which are ancient forms).
