U+721E "爞" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

U+721E "爞" CJK Unified Ideograph-# is a complex Chinese character, known as a Hanzi, that primarily refers to a type of plant or herb, often identified with the meaning of "smoke" or "soot" in its archaic or highly specialized usages, though it is extremely rare in modern standard Chinese. This character falls under the fire radical (火) and is composed of multiple components, including the character for "winter" (冬) repeated, contributing to its structure and historical phonetic or semantic associations. In classical texts, such as ancient dictionaries or poetry, 爞 appears infrequently, typically describing the haze or dark, smoky quality of wildfires or burning substances. Today, it is largely obsolete in everyday language and is valued more for its linguistic and historical interest in the study of Chinese character evolution and orthography, representing a niche piece of the vast CJK Unihan repertoire.
