U+538E "厎" CJK Unified Ideograph-# Unicode Character
U+538E "厎" CJK Unified Ideograph-# is a Chinese character used in both classical and modern written texts, primarily functioning as a variant of the more common character "底" (dǐ), meaning "bottom," "base," or "foundation." In its traditional usage, "厎" can also carry the sense of "to smooth" or "to polish a stone," reflecting its etymological roots in ancient Chinese where it was associated with the action of grinding or refining. This character is composed of the radical "厂" (cliff) on the outer left, with the phonetic component "氏" beneath, and it appears in historical literature, such as in classical texts like the "Shuowen Jiezi," where it is defined as a type of whetstone. Today, it is recognized within the Unicode standard for digital text representation, particularly in contexts involving complex traditional Chinese characters or historical linguistic studies.
