The Chinese word "卡塔尔" is formed through phonetic transliteration, where each character is chosen to approximate the sounds of the English name "Qatar": "卡" (kǎ) corresponds to "Qa", "塔" (tǎ) corresponds to "tar", and "尔" (ěr) is added as a neutral suffix commonly used in Chinese to adapt foreign names, completing the sound-based representation without conveying independent meaning.
