Curtesy or Courtesy: Which Spelling Is Correct?

If you are wondering whether “curtesy” or “courtesy” is the correct spelling, the answer is courtesy for the common word meaning polite behavior, respect, or a considerate act. For example, “She treated everyone with courtesy.” Curtesy is a real but uncommon word with a different historical legal meaning, so it is not the spelling you normally want when talking about politeness.

These two words are easy to confuse because they look and sound similar. However, they are not interchangeable. Understanding the difference can help you avoid spelling mistakes in school assignments, emails, professional writing, and everyday communication. In most situations involving good manners, respectful behavior, or polite treatment, courtesy is the correct choice.

Quick Answer

Courtesy is the correct spelling when you mean politeness, good manners, respect, or a considerate action. Curtesy is an uncommon historical legal term referring to a husband’s right to certain property interests connected with his deceased wife. For everyday English, use courtesy.

Why Do People Confuse “Curtesy” and “Courtesy”?

People often confuse these words because they have similar spellings and pronunciations. The extra “o” in courtesy is easy to overlook when writing quickly.

There is also a pronunciation difference that can make the spelling less obvious. In modern English, courtesy is the familiar word, while curtesy is rarely encountered outside historical or legal contexts.

If you are writing about:

• politeness
• good manners
• respect
• kindness
• considerate behavior
• a polite gesture

you almost certainly need courtesy.

What Does “Courtesy” Mean?

Courtesy is a noun meaning polite, respectful, or considerate behavior toward another person.

It can also describe a polite action or something provided as a favor or gesture.

Examples

What Does “Curtesy” Mean?

Curtesy is a rare historical legal term. Traditionally, it referred to a husband’s right to certain interests in property that belonged to his deceased wife, particularly under older English law.

This meaning is very different from courtesy.

Because curtesy is uncommon in modern everyday English, most writers will never need to use it. If you are talking about manners or respectful behavior, curtesy is not the word you want.
