The Chinese word 演示 is formed by combining two meaningful characters, each contributing to its overall concept. The first character, 演, carries meanings related to performing, developing, or evolving an action. The second character, 示, means to show, indicate, or display. When combined, the characters create a compound where 演 describes the act of performing a process and 示 specifies the purpose of that act: to show it to others. Thus, the word literally and conceptually means "to perform and show", which perfectly captures its modern meaning of "to demonstrate".
