Courtesy and curtesy look almost identical and sound very similar, so it is easy to mix them up. But in modern standard English, courtesy is the spelling you need when you mean politeness, good manners, or a polite action.
Curtesy is a rare historical word with a completely different legal meaning. It is not the normal spelling of courtesy.
If you are writing an email, article, school assignment, business message, or everyday sentence, choose courtesy.

So, What Is Curtesy?
Curtesy is a rare and largely historical legal term. It is not a spelling variant of modern courtesy.
In historical English law, curtesy referred to certain rights a husband could have in property belonging to his deceased wife, subject to specific legal conditions.
Because this is an old legal concept, you are unlikely to encounter curtesy in ordinary conversation or modern general writing.
Example of its specialized use
The historical document discussed the husband’s right of curtesy.
For normal situations involving manners or politeness, use courtesy.
Pronunciation: Why Are They So Easy to Confuse?
The standard pronunciation of courtesy is approximately:
KUR-tuh-see
IPA: /ˈkɜːrtəsi/ in many British pronunciations and /ˈkɝːtəsi/ in American English.
Curtesy is also pronounced similarly in its historical/legal use.
That means pronunciation is not a reliable way to decide which spelling you need.
The meaning matters.
| Word | Approximate pronunciation | Everyday word? |
|---|---|---|
| Courtesy | KUR-tuh-see | Yes |
| Curtesy | KUR-tuh-see | Rare/historical |
Singular and Plural Forms
Courtesy

Plural: courtesies
Examples:

Curtesy

The plural is possible in historical/legal writing, but the word is extremely uncommon compared with courtesy.

Where Did Courtesy Come From?
The word courtesy is connected to the idea of behavior expected at a court, particularly the manners and refinement associated with a royal or noble court.
It developed through French and Middle English and eventually acquired the broader modern meaning of polite, respectful behavior.
The historical connection with courtly behavior explains why courtesy is associated with:
- manners
- respect
- politeness
- proper behavior
Curtesy, despite looking almost identical, developed as a separate historical legal term.
That is why the two words should not be treated as simple spelling alternatives.
