The Chinese word "欧莱雅" is formed through phonetic transliteration, where each character is chosen primarily for its sound to approximate the foreign brand name "L'Oreal". The character "欧" (Ōu) corresponds to the "L'O" sound, "莱" (lái) to the "ré" sound, and "雅" (yǎ) to the "al" sound, resulting in a combined pronunciation that mimics the original. This method creates a recognizable Chinese equivalent without direct semantic meaning from the individual characters.
