The kanji 燥 is a phono-semantic compound (形声文字, keisei moji). It is composed of two parts: the radical 火 (火), meaning "fire" or "heat," and the phonetic component 喿 (sō), which contributes to the sound and, by extension, the meaning. The presence of the 火 radical hints at the drying effect of heat, associating the character with the removal of moisture, which happens through heat. The original meaning evolved from the action of drying something using heat.
