The Chinese word 史蒂文 is formed through phonetic transliteration of the English name "Steven" or "Stephen", where each character represents a syllable: 史 (shǐ) approximates "Ste", 蒂 (dì) approximates "ven" or "phen", and 文 (wén) approximates the final sound, with the characters chosen solely for their phonetic resemblance without regard to their original meanings.
