7.113

乾燥（上古寒反字樣云本音䖍今借為乾溼字也古文從水作漧下蘇道反玉篇火乾也切韻云乾亦燥也）。

乾燥 [Dry and parched]: The upper [character] has the fanqie 古寒 (gǔ + hán = gān); the Ziyang says, “Its original sound was 䖍, but it is now borrowed for dry versus wet.” The ancient script derives it from 水 as 漧. The lower [character] has the fanqie 蘇道 (sū + dào = sào); the Yupian says, “Dried by fire.” The Qieyun says, “乾 is also parched.”
