The Chinese word "纳尔逊" is formed solely through phonetic transliteration of the foreign name "Nelson". Each character is chosen for its sound: "纳" (nà) approximates "Nel", "尔" (ěr) approximates "son", and "逊" (xùn) is added to better capture the overall pronunciation of "Nelson" in Chinese, with the characters carrying no semantic relevance to the original name.
