The Chinese word "贝尔" (Bèi'ěr) is a phonetic loanword formed through transliteration, specifically designed to approximate the sound of the foreign name "Bell" (as in Alexander Graham Bell). It is constructed by selecting two existing Chinese characters, 贝 (bèi) and 尔 (ěr), whose combined pronunciation closely mimics the English source. This is a standard method in Chinese for adapting foreign names and terms, where characters are chosen primarily for their sound rather than their meaning, resulting in a word that is phonetically familiar but semantically non-literal to Chinese speakers.
