U+5416 "吖" CJK Unified Ideograph-# Unicode Character

U+5416 "吖" CJK Unified Ideograph-# is a Chinese character that primarily functions as a phonetic component in the pronunciation of various words, often representing the sound "ā" or "ya" in Mandarin. It is commonly used in the transliteration of foreign names and terms, such as in the word "吖啶" for the chemical compound acridine, and also appears in colloquial or dialectal expressions, though it lacks a standalone concrete meaning in standard modern Chinese. Its structure is composed of the mouth radical "口" on the left and the phonetic element "阿" on the right, reflecting its role in sound representation within the CJK (Chinese, Japanese, Korean) script system.
