爵士
jué shì · HSK 7
jazz
🎷 jué shì echoes jazz; 爵 noble rank + 士 gentleman = a Sir or knight
The loanword 爵士 (jué shì) was picked because it sounds like the English word jazz. The very same two characters literally mean a noble rank (爵) plus a gentleman or scholar (士), which is how they also mean Sir or knight.
