The kanji 砂砂 is a phono-semantic compound (形声文字). The left side is the radical 石 (ishi), meaning "stone" or "rock". The right side is 少 (shou), which originally means "few" or "little". The combination suggests "small pieces of stone", thus referring to sand. The 石 radical indicates the nature of sand being related to rocks or minerals. The shape evolved over time, showing how the original form combined the meaning of stone (rock) and the sense of smallness or abundance.
