The word 慑人 is formed by combining the character 慑, meaning to frighten, which itself consists of the heart radical 忄 indicating emotion and the phonetic component 聂, with the character 人 meaning person. This combination creates a verb-object structure where 慑 acts as the verb for frightening and 人 serves as the object, resulting in a literal meaning of "to frighten people" and used to describe something terrifying or awe-inspiring.
