The Origin of Curtesy Or Courtesy →
The word courtesy comes from Old French courtoisie. It later entered Middle English. The root word is “court.” Long ago, people at royal courts were expected to behave politely. Good manners became known as “courtesy.”
Over time, English kept the spelling courtesy. The spelling curtesy appeared as a mistake because people spelled the word by sound.
