The word "弗兰克" is formed through a purely phonetic process called transliteration, where the sounds of the foreign name "Frank" are approximated using existing Chinese characters that have similar pronunciations. Each character (弗 fú, 兰 lán, 克 kè) is selected not for its meaning, but for its sound, to mimic the syllables of the original name. This creates a new word that functions solely as a phonetic vessel, carrying no inherent semantic content related to the characters' original meanings.
