The kanji 刷 is a phono-semantic compound (形声文字) formed during the Shuowen Jiezi era in China. Its structure combines the radical 刂 (刀, "knife" or "blade") on the right, which indicates its meaning category related to cutting or carving, with the component 尸帀 on the left, which primarily serves as a phonetic component. This 尸帀 element is a corrupted form of an earlier character, and it provides the approximate sound "satsu". The original conceptual meaning was "to scrape" or "to pare," an action performed with a blade. Historically, the character's evolution is tied to the development of printing technology. The core concept of using a knife to carve is directly linked to woodblock printing, where characters were meticulously carved in reverse onto a wooden block. The semantic shift from the physical act of carving ("to scrape") to the modern meaning of "printing" or "to print" occurred because the carved block was the essential tool for producing copies. The process of applying ink to the carved block and pressing it onto paper became synonymous with the character itself. The character 刷 was transmitted to Japan along with the bulk of Chinese writing, almost certainly by the Nara period (710-794 AD) or earlier, as part of the cultural importation of Chinese literature and technology. The technique of woodblock printing itself was also imported from China and became highly refined in Japan. A key linguistic note is the Japanese kun'yomi "sur-u," which retains the original sense of "to rub," "to print," or "to scrub." This reading perfectly captures the physical action of rubbing paper against an inked woodblock to create a print, demonstrating how the character's ancient etymology is preserved in its Japanese usage.
