⚫︎成功（せいこう） Translation: Success ⚫︎成人（せいじん） Translation: Adult ⚫︎完成（かんせい） Translation: Completion

The kanji 成 is a pictophonetic character. The left side is a part of the character 戊 (bo or tsuchinoe), a character that resembles an axe. The right side is 囗 (kuni-gamae) which represents an enclosure or a boundary. The original meaning might have been related to completing a construction or achieving a result. The combination suggests that an outcome (the result of the 戊, which is the axe, working within the enclosed area) is achieved or formed. The character's form has evolved over time, but the core meanings of achievement and completion have remained consistent.
