3.13

驚駭（上舉卿反怖也下候揩反切韻云駭亦驚也說文云從馬亥聲孫然注爾雅云禹疏九河北河功難眾懼不成因名徒駭也）。

驚駭 (The first character is pronounced 舉 + 卿 fanqie: frightened. The second character is pronounced 候 + 揩 fanqie. The Qieyun says: 'Hai also means alarmed.' The Shuowen jiezi says: 'Formed with 馬 as semantic and 亥 as phonetic.' Sun Ran's commentary on the Erya says: 'When Yu dredged the Nine Rivers, the work on the northern river was arduous; the multitudes were terrified [juhai] that it would not be completed, hence it was named the Tuhai River').
