The word 尽量 is formed by combining two characters: 尽, which carries the core meaning of "to exhaust" or "to reach the limit", and 量, which means "capacity" or "measure". Their combination creates a conceptual whole meaning "to the greatest extent of one's capacity" or "as much as possible", where 尽 acts upon the boundary implied by 量, effectively conveying the idea of pushing to the feasible limit without exceeding it.
