The word 稳定 is formed through the conceptual fusion of its two component characters: 稳, which carries the core idea of being steady, firm, or secure (like a steady hand or a secure footing), and 定, which means fixed, settled, or decided. By combining them, the word visually and semantically portrays the process or state where steadiness leads to a settled, fixed condition, ultimately conveying the integrated meaning of "stable" or "stability".
