The word "欺诈" is formed by combining the characters "欺" and "诈", both meaning deception. "欺" denotes cheating or deceiving, structured with the radical "欠" (suggesting lack or debt) and the phonetic component "其". "诈" means swindling or pretending, composed of the radical "讠" (related to speech) and the phonetic component "乍". Together, they create a compound where each character reinforces the other, resulting in the meaning of fraud or deceit.
