The word 实力 is formed through a conceptual fusion where 实 (shí), meaning "solid", "real", or "substantial", provides the foundational quality of concrete existence and genuine content. This is combined with 力 (lì), meaning "strength", "power", or "capability", which represents dynamic force and effectiveness. Together, they create a compound where inherent, tangible substance (实) becomes the source and substance of one's effective power or competitive strength (力), embodying the idea of real, demonstrable ability rather than superficial appearance or potential alone.
