The kanji 擦 is a phono-semantic compound (形声文字, keisei moji). The semantic component is 手 (te), meaning "hand," providing the meaning of action done by hand. The phonetic component is 察 (satsu), which contributes to the sound of the kanji. Therefore, the formation suggests the use of the hand ("hand") to rub or scrape, influenced by the sound of 察.
