The word 纯净水 is formed by combining three characters: 纯 (chún), meaning "pure"; 净 (jìng), meaning "clean"; and 水 (shuǐ), meaning "water". The characters 纯 and 净 are first joined to create the compound 纯净, meaning "pure and clean", which then modifies 水 to specify the type of water, resulting in the term for "purified water".
