The word "保罗" is formed through phonetic transliteration, where the character "保" (bǎo) is selected for its syllable approximating "Pau" and "罗" (luó) for its syllable approximating "l", together creating the sound "Bǎoluó" to mimic the English name "Paul". The individual meanings of the characters, "保" meaning to protect and "罗" meaning to net or collect, are not relevant to this construction, as the word is assembled solely based on sound correspondence.
