逻辑
luó ji
(loanword) logic
patrol (逻) + compile (辑) = logic (sound-borrowed loanword)
逻辑 is a phonetic transcription of the English word 'logic' — the characters were chosen to approximate the sound luó ji, not to carry the meaning. The individual components of each character play no role in the word's meaning here.
