The word "聪慧" is formed by combining two characters: "聪" and "慧". "聪" is a phonetic-semantic compound where "耳" (ear) indicates its semantic field related to hearing or perceptiveness, and "总" primarily provides phonetic guidance. "慧" is also a phonetic-semantic compound with "彗" serving as the phonetic component and "心" (heart/mind) denoting its association with mental faculties. Together, the characters form a compound word where "聪" contributes the sense of acute perception and "慧" adds the aspect of wisdom, resulting in the meaning of intelligence or cleverness.
