The word 最终 is formed through a conceptual combination where the first character 最 (meaning "most" or "utmost") acts as an intensifier applied to the second character 终 (meaning "end" or "conclusion"). This creates a fused idea of the "utmost end" or the "furthest point in a sequence", thereby arriving at the meaning of "final" or "ultimate". It is a straightforward compounding of two meaningful units where the first modifies and elevates the fundamental notion of the second.
