señor
/seˈɲoɾ/ · A1 · adj
mister, sir, lord
🎩 señor = senior: Latin senior (older) became the title for a respected man
From Latin senior, meaning older, the same root as English senior and sir. The elder became the lord, then simply mister. Placed before a noun as an adjective it adds weight: un señor coche is a great big, whopping car.
