Origin

The character 裕 combines clothing or fabric on the left (衤) with a sound hint on the right (谷, which suggests the pronunciation). The left component originally referred to garments, and over time the character expanded to mean "spacious" or "loose-fitting" — the idea of cloth with plenty of room in it. From this sense of spaciousness and room to spare, the meaning broadened to "abundant" and "rich," capturing the feeling of having more than enough. The sound component 谷 guided readers roughly toward the pronunciation ユウ (yu).
