The Chinese word "库克" (Kùkè) is a **phonetic transcription** formed through the common practice of **transliteration**, specifically used to represent the English surname "Cook," most notably referring to Tim Cook, the CEO of Apple. Each character is chosen not for its meaning but for its sound: "库" (kù) approximates the "Coo-" sound, while "克" (kè) approximates the "-k" sound. This method of creating new words by borrowing sounds from foreign languages is a standard way to adapt foreign names into Chinese, resulting in a term whose primary function is to provide an aural equivalent rather than convey a semantic meaning.
