Origin

The character 概 combines a wood radical on the left, which groups it with characters about wooden objects or structures, with the component 既 on the right that serves as a sound hint for the pronunciation "gai." The left side's wood component most likely originally depicted a wooden scraper or straightedge tool used to level or smooth surfaces. From this practical tool meaning came the idea of scraping away details or reducing something to its bare outline—which connects to the character's meanings of "outline," "approximation," and "generally." Over time, the visual reference to the scraping tool faded, but the abstract notion of stripping down to essentials remained.
