The kanji 策 (さく) is a 形声文字 (keisei moji), a phono-semantic compound. It combines the phonetic component 朿 (shi), which represents the sound, and the radical 竹 (take), meaning "bamboo." The bamboo radical suggests that the original meaning of 策 was related to bamboo slips used for writing and recording plans. Over time, the meaning expanded to encompass strategies and plans in general.
