U+4E0D "不" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
不
U+4E0D "不" CJK Unified Ideograph-# is a fundamental and widely used character in Chinese, Japanese, and Korean (CJK) scripts, primarily meaning "not" or "no" and serving as a common negative prefix. Its structure is categorized under the Kangxi radical for "one" (一) with a total of four strokes, and it appears in countless compounds like "不好" (bù hǎo, "not good") or "不行" (bùxíng, "not allowed"). This ideograph directly negates verbs, adjectives, and entire phrases, making it essential for constructing negative statements across East Asian languages. Due to its simplicity and frequency, it is one of the first characters learned by students of these writing systems.
