The word "聘用" is formed by combining the characters "聘" and "用". "聘" is composed of the semantic component "耳" (ear), which historically relates to listening or consultation in the context of inviting someone, and the phonetic component "甹" that suggests its pronunciation. "用" is a pictographic character originally depicting a bucket, conveying the meaning of use or employment. Together, "聘" denotes the act of engaging or recruiting, while "用" signifies utilization, resulting in a compound word meaning to hire or employ.
