About
The character "擀" is a relatively late formation in Chinese writing, appearing in dictionaries by at least the Ming dynasty. Its traditional form is identical to its simplified counterpart, "擀", and is structurally composed of the hand radical (扌) on the left, indicating a hand action, combined with the phonetic and semantic component "幹" (gàn) on the right, which contributes both sound and a sense of 'main stem' or 'working', implying a forceful, linear motion. The character's core meaning has consistently been the specific action of rolling out dough or flattening something with a rolling pin, a narrow and technical sense that has remained stable. While its use is primarily concrete, it can occasionally extend to similar pressing or flattening actions in other contexts, but this is not a significant semantic shift.
