sir
UK: sɜː(r) | US: sɝː
n. a formal or polite title used to address a man, especially in authority or of higher social rank
n. (historical) a title for a knight or baronet
The word "sir" originates from Middle English sire, borrowed from Old French sire (meaning "lord" or "master"), which itself derives from Latin senior (meaning "older" or "superior"). Over time, it evolved into a respectful term of address for men, particularly those in positions of authority or nobility. The Latin root senior also gives rise to words like "senior" and "senate," reflecting its connection to age and status.
