The word "利息" is formed by combining the character "利", which signifies profit or benefit and is etymologically derived from the pictorial representation of harvesting grain with a knife, indicating gain, with the character "息", which denotes interest or growth and is composed of elements suggesting breath or offspring emanating from oneself, conveying the idea of accrual. In this compound, "息" specifically refers to the increment on capital, while "利" reinforces the notion of financial return, together constituting the term for monetary interest.
