The word "尘嚣" is formed by combining the character "尘", meaning dust, which etymologically derives from the radicals "小" (small) and "土" (soil) to indicate fine particles, with the character "嚣", meaning clamor, which is composed of four "口" (mouth) radicals surrounding "页" (head) to depict loud noise. Together, they create a compound where the literal elements of dust and noise merge to represent worldly hustle and bustle.
