Origin

The character combines bamboo at the top with a component meaning small or limited at the bottom. Since bamboo was a traditional material for writing in East Asia, this combination creates the idea of thin bamboo strips used for writing. The addition of the "small" element emphasizes these as modest writing surfaces—the kind of thin strips, labels, or notes that would have been common before paper became widespread. Over time, the meaning expanded to cover paper and written compositions more broadly, while the bamboo radical remained as a classifier indicating the material's origin.
