The word "撒旦" (Sàdàn) is formed through a process of phonetic transliteration, where existing Chinese characters are chosen purely for their sound to approximate the pronunciation of the foreign term "Satan". The characters 撒 (sā) and 旦 (dàn) individually carry their own unrelated meanings (e.g., "to cast" and "dawn"), but here they are combined solely to replicate the auditory profile of the original name. Thus, the formation is not based on meaning, but on creating a recognizable sound bridge, allowing the concept to be integrated into the Chinese language while clearly marking it as a borrowed, proper noun.
