About
The character "咭" is a phono-semantic compound formed by the mouth radical (口) and the phonetic component "吉", which originally associated it with vocal sounds such as chirping or laughter. Its etymology is rooted in onomatopoeic functions, but through phonetic borrowing, it later acquired additional meanings, as seen in the term "咭片" for "card". The structure of the character remains unchanged, with its traditional form consistently reflecting these dual roles in language use.
