U+5421 "吡" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

吡

U+5421 "吡" CJK Unified Ideograph-# is a Chinese character primarily used as a phonetic component in loanwords and transliterations, often representing sounds like "bi" or "pi" in Mandarin. It can be found in terms such as "吡啶" (pyridine) in chemistry or "吡咯" (pyrrole), where it functions as a transliteration of the "py" sound from Western scientific vocabulary. While it appears in some classical or literary contexts with meanings related to scolding or a humming sound, its modern usage is overwhelmingly limited to technical and borrowed terminology rather than everyday language. This character is encoded in the CJK Unified Ideographs block of the Unicode standard, part of the broader set of characters used for writing Chinese, Japanese, and Korean.
