The word 散发 is formed by combining two characters, each contributing a key visual and conceptual element to create a unified meaning. The first character, 散, originally depicted a hand (扌) separating bamboo slips (朿), conveying the idea of scattering, loosening, or dispersing. The second character, 发 (發), shows a foot (癶) launching an arrow (弓), representing the action of sending out or emitting. When paired, they create a compound ideograph where the action of "sending out" (发) is inherently performed in a "scattered, diffuse manner" (散), pictorially merging into the concept of to distribute, to emit, or to give off freely.
