The Chinese word 弗洛伊德 is formed through phonetic transcription, where each character is chosen solely for its sound to approximate the pronunciation of the English name "Freud": 弗 (fú) for "Fre", 洛 (luò) for "lo", 伊 (yī) for "y", and 德 (dé) for "d", resulting in the sequential combination that mimics the original name's syllables.
