U+2F1D "⼝" Kangxi Radical Mouth Unicode Character

Unicode Version 17.0

U+2F1D "⼝" Kangxi Radical Mouth is a graphical representation of the 30th radical in the Kangxi system of Chinese character classification, symbolizing the concept of a mouth or an opening. This radical is a fundamental component in thousands of Chinese characters, often conveying meanings related to speech, eating, or enclosure, such as in 口 (kǒu) meaning “mouth” or 吃 (chī) meaning “to eat.” In Unicode, it belongs to the Kangxi Radicals block, which encodes these historical character components separately from their full CJK forms for specialized use in dictionaries and linguistic contexts. Its distinctive square shape with a central void serves as a building block for more complex logograms across Chinese, Japanese, and Korean writing systems.
