The word 终究 is formed by combining two characters, 终 and 究, which both individually carry connotations of reaching a final point or conclusion. 终 means "end" or "finally", emphasizing the terminal point of a process, while 究 means "to investigate to the end" or "after all", conveying a sense of exhaustive pursuit leading to a definitive result. Their union creates a single concept that intensifies and encapsulates the idea of an inevitable, ultimate outcome, blending their shared semantic field of finality into a cohesive expression meaning "in the end" or "after all".
