The Kanji: 楷 (Kai)
The kanji 楷 (read as kai) primarily means "model," "pattern," or "standard form." It is composed of the wood radical (木) and the component 皆 (all, everyone), suggesting a "wooden model" or a standard for all to follow. In its most specific and important usage, it refers to a fundamental style of Chinese and Japanese calligraphy.
