What Is Curtesy?
Although uncommon today, curtesy is a real historical English word.
It has two primary meanings.
1. Historical Spelling of Courtesy
Centuries ago, English spelling wasn’t standardized.
As a result, writers often used:
- Curtesy
- Courtesy
- Curtesie
- Curtesie
These variations referred to the same concept of politeness.
Today, this spelling is considered outdated.
2. Legal Meaning
Historically, curtesy also referred to a legal doctrine known as:

Under old English common law, a widower could inherit a life interest in his deceased wife’s property under certain conditions.
Modern legal systems have largely abolished or replaced this doctrine, making the term uncommon outside legal history.
Why Courtesy Became the Standard Spelling
English spelling gradually became standardized through:
- Dictionaries
- Printing presses
- Education systems
- Publishing standards
As spelling became more consistent, courtesy emerged as the accepted modern form.
Today, dictionaries, schools, businesses, and style guides all recommend courtesy for everyday writing.
