About
The character "蓰" is structured with the grass radical (艹) positioned above the component "徙", which carries the meaning of moving or migrating. Etymologically, it originally referred to a kind of plant or grass in early classical usage, but its meaning shifted to denote a specific multiplicative factor, particularly a fivefold increase, as evidenced in ancient texts such as the Mencius. This quantitative sense, indicating multiplication by five or generally a multiple, eventually became the character's primary semantic function, moving away from its botanical associations. The traditional form "蓰" has maintained this compositional structure throughout its history, with no simplified variant developed, and its modern application is largely confined to literary or fixed expressions reflecting this arithmetic concept.
