U+583F "堿" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

堿

U+583F "堿" CJK Unified Ideograph-# is a Chinese character (hanzi) used primarily in traditional and simplified Chinese writing, where it is a variant form of the character "鹼" or "碱," both meaning "alkali" or "base" in a chemical sense. This ideograph is composed of the radical "土" (earth or soil) on the left and "咸" (salty) on the right, reflecting its original reference to alkaline salts found in soil or water. In modern usage, it appears in contexts related to chemistry, traditional medicine, and agriculture, though it is less common than its standardized counterparts, particularly in simplified Chinese where "碱" is preferred. As part of the CJK (Chinese, Japanese, Korean) unified ideographs block, it encodes a specific glyph shared across these languages, with its reading and usage varying slightly in Japanese and Korean, where it similarly denotes alkaline substances.
