Do you write “courtesy” or “curtesy” when you mean polite behavior? You are not alone if you pause before typing this word. These two terms look almost the same, but only one fits everyday writing.
In this guide, you will learn the true meaning of each word, see clear examples, and avoid the common mix up that trips up even confident writers. By the end, you will know exactly which word to use and why.
Define Courtesy
Courtesy is a noun that means polite behavior, respect, and good manners shown toward other people. It covers small acts like saying please, holding a door open, or thanking someone for their time.
The word comes from “court,” tied to the polished manners expected in royal courts long ago. Today, it simply means kindness in action.
Key points about courtesy:
- It is the correct spelling in almost every situation.
- It can describe an action, a remark, or a general manner.
- It often appears in phrases like common courtesy, courtesy call, and courtesy car.
Define Curtesy
Curtesy is a rare legal term. It refers to a husband’s right, under old common law, to his deceased wife’s property if the couple had children together who could inherit.
This word has nothing to do with politeness. It belongs to historical property law and almost never appears in modern writing outside legal or academic texts.
Key points about curtesy:
- It is spelled without the second “o.”
- It applies only to inheritance and property law.
- Most modern legal systems have replaced it with updated inheritance rules.
Courtesy vs curtesy meaning
The meanings of these two words could not be more different.
| Word | Part of Speech | Meaning | Common Use |
| Courtesy | Noun | Politeness, respect, good manners | Everyday speech, business writing, customer service |
| Curtesy | Noun | A husband’s legal right to a deceased wife’s property | Legal documents, historical law, academic study |
Courtesy is about how people treat each other. Curtesy is about who owns what after a death. Once you see them side by side, the difference becomes easy to remember.
How To Properly Use The Words In A Sentence
Knowing the meaning is only half the job. You also need to know how each word fits naturally into a sentence.

In nearly every piece of writing you create, from emails to social posts, courtesy is the word you need.
Common Mistakes To Avoid
Even skilled writers slip up with these two words. Here are the most frequent errors and how to fix them.
1. Using “Curtesy” Instead of “Courtesy”
This is the most common mistake. People drop the second “o” by accident, often because the words sound nearly identical when spoken aloud.
- Wrong: Please show curtesy to your guests.
- Right: Please show courtesy to your guests.
2. Using “Courtesy” as a Verb
Courtesy is a noun. It is not something you do directly as an action word.
- Wrong: I will courtesy him at the meeting.
- Right: I will show him courtesy at the meeting.
3. Confusing Courtesy With Respect
Courtesy and respect are related, but they are not the same thing. Courtesy refers to polite gestures and behavior. Respect refers to genuine admiration or esteem for someone.
- Courtesy example: He held the door open out of courtesy.
- Respect example: She earned the team’s respect through years of hard work.
Tips To Avoid These Mistakes
- Remember that courtesy contains the word “court,” which hints at polished, courtly manners.
- Remember that curtesy drops the “o,” matching its narrow, old fashioned legal use.
- Read your sentence aloud. If it relates to kindness or manners, courtesy almost always fits.
- Run a quick spell check, since curtesy is a real word and will not get flagged automatically.
Context Matters
Word choice always depends on context. A business email, a customer service note, or a thank you card will almost always call for courtesy. A property law case, a history paper, or an old legal document might require curtesy.
When in doubt, picture the setting. Everyday life, workplace communication, and casual writing call for courtesy. Formal legal study calls for curtesy.
Exceptions To The Rules
While courtesy fits most situations, a few specific fields still use curtesy or keep older spelling habits alive.
1. Legal Terminology
Curtesy remains a recognized term in property and inheritance law, even though many modern systems have replaced it with newer rules. Law students and legal historians still need to know this word.
2. Heraldry
Some historical and heraldic texts preserve older spellings and legal terms tied to inheritance and noble titles, including references to curtesy.
3. Everyday Communication
Outside of legal study, curtesy almost never appears. If you see it in a casual email or social media post, it is almost always a spelling mistake for courtesy.
courtesy or curtesy meaning
To summarize the meaning one more time:
- Courtesy means polite, respectful, and considerate behavior.
- Curtesy means a husband’s old legal right to a deceased wife’s property.
If you are writing about kindness, manners, or respect, courtesy is correct. If you are writing about a specific historical property law, curtesy is correct.
