Courtesy Vs Curtesy Pronunciation Guide

Courtesy

Curtesy

Courtesy Vs Curtesy Etymology And Word Origin

Courtesy

The word traces back through Latin to the idea of a “court.” In Old French, cort meant “court,” and corteis meant “courtly.” From that came cortesie, meaning refined, polite behavior. Medieval courts set the standard for good manners, so the word came to mean politeness in general. It entered English in the Middle English period.

Curtesy

Middle English spelling was flexible, so you will find forms such as curtesie and courtesie for the same word. Over time, the “ou” spelling became standard, which matches the word “court.” The “u” spelling lingered in law, and the legal doctrine became known as “curtesy.” The bow “curtsy” is also a later variant of “courtesy,” which explains why these words look so alike.
