The Chinese word 伊戈尔 is formed through phonetic transliteration, where each character is selected solely for its sound to approximate the foreign name "Igor": 伊 (yī) represents the initial "I" sound, 戈 (gē) captures the "gor" syllable, and 尔 (ěr) provides the final "r" sound, combining to create a close auditory match in Mandarin.
