The kanji 沙 generally represents "sand" or "sandy." It refers to fine particles of rock or mineral, typically found on beaches, in deserts, or in riverbeds. The character evokes images of loose, granular material.

⚫︎ 砂浜（すなはま） Translation: Sandy beach ⚫︎ 砂漠（さばく） Translation: Desert ⚫︎ 砂糖（さとう） Translation: Sugar (literally "sand sugar," because of its granular texture)

The kanji 沙 is a phono-semantic compound (形声文字, けいせいもじ). The left side is the radical 氵（さんずい, さんずい), which represents "water" or "liquid". The right side is 少（しょう）, which is originally a phonetic component, and indicates the sound of the kanji. The combination suggests something related to "water" and "small particles," therefore "sand".
