The Chinese word 竭尽 (jiéjìn) is a compound verb formed through the combination of two synonymous or near-synonymous morphemes, each contributing to an intensified meaning of exhaustive completion. The first character, 竭 (jié), originally conveys the idea of draining, depleting, or using something up until it is dry or empty. The second character, 尽 (jìn), means to exhaust, finish, or reach a limit. When paired, these characters reinforce each other to create a single, powerful verb meaning "to exhaust completely", "to use up to the utmost", or "to spare no effort", emphasizing a thorough and total depletion of resources, energy, or effort toward a specific end. This type of word formation, where components with similar meanings combine for emphasis, is common in Chinese lexical construction.
