The word "威尔逊" (Wēi'ěrxùn) is a phonetic loanword formed through transliteration, specifically designed to represent the sounds of the foreign name "Wilson" in Chinese characters. It is constructed by selecting characters whose modern Mandarin pronunciations (wēi, ěr, xùn) closely approximate the syllables of the original English name, with no regard for the literal meanings of the individual characters (which roughly translate to "power", "you", and "fast" respectively). This is a standard method in Chinese for adapting foreign proper nouns, especially personal surnames, creating a meaningful written form only in its collective phonetic function.
