Have you ever heard someone say “ditto” and wondered if it should be spelled ditto or diddo? This is a common spelling confusion, especially among English learners and people who hear the word before seeing it in writing.
Ditto is the correct spelling. Diddo is a misspelling when you mean “the same” or “I agree.” The word ditto is used in everyday conversations, text messages, and informal writing. It can show that you share someone’s opinion, feeling, or experience.
For example, if someone says, “I love this song,” you can reply, “Ditto!” This means “I love it too” or “I feel the same way.”
But what exactly does ditto mean? Where did the word come from? Is it appropriate for formal writing? And why do so many people spell it as diddo?
In this guide, you will learn the correct spelling, meaning, origin, pronunciation, common mistakes, and practical examples of ditto. You will also discover how to use it naturally in different situations.
Let’s begin by settling the spelling question.
Ditto or Diddo: Quick Answer
Ditto is the correct spelling. Diddo is incorrect when you want to express “the same,” “me too,” or “I agree.”
The word ditto has two common uses:
- It means “the same” when referring to repeated information.
- It means “I agree” or “me too” in casual conversations.
Examples:
- “I am tired today.” “Ditto!”
- “She bought a blue notebook, and I bought ditto.”
- “I love your new hairstyle.” “Ditto!”
The main rule is simple: Use ditto, not diddo, in standard English.
What Does Ditto Mean?
Ditto is an English word that means “the same” or “the same thing as mentioned before.” It can also be used as a short response to show agreement.
The meaning depends on the situation.
1. Ditto Means “The Same”
When you use ditto to refer to something repeated, you are saying that the same information applies again.
Example:
The first box contains ten books. The second box contains ditto.
In this example, ditto means that the second box also contains ten books.
A more natural modern version would be:
The second box also contains ten books.
2. Ditto Means “I Agree”
In informal conversations, ditto can mean “I agree,” “me too,” or “I feel the same way.”
Example:
“I really enjoyed the movie.”
“Ditto!”
The second speaker is saying that they also enjoyed the movie.
3. Ditto as a Repetition Mark
A ditto mark is a symbol used to show that information is repeated from above. The symbol is often written as two small quotation marks or represented by a double prime like mark.
For example, an old record might use ditto marks to repeat a name or a category in a list.
Today, many documents repeat the information directly because it is easier to read.
4. Ditto as a Verb
Ditto can also be used as a verb, meaning to repeat or do the same thing.
Example:
“Please ditto the instructions from the previous page.”
This use is less common than the conversational meaning.
The Origin of Ditto
The word ditto entered English from Italian. It is connected to the Italian word detto, which means “said” or “the said.”
The word became popular in English record keeping and commercial documents. People used it to indicate that information was the same as something written above.
Over time, ditto developed a wider meaning. It began to refer to anything repeated or identical.
Eventually, people started using ditto in everyday speech as a short way to agree with someone. This conversational use is still familiar today.
Why Do People Spell Ditto as Diddo?
The spelling diddo usually comes from a pronunciation based mistake.
When people hear ditto, they may not know how to spell it. Because the word is pronounced quickly in conversation, some people write diddo instead.
However, diddo is not the standard spelling of the word meaning “the same” or “I agree.”
How Do You Pronounce Ditto?
Ditto is usually pronounced DIT oh.
- Dit sounds like the beginning of the word difficult.
- Oh sounds like the letter O.
The pronunciation does not change the spelling. Remember the two T’s in ditto.
British English vs American English
There is no spelling difference between British English and American English for the word ditto. Both varieties use the same spelling.
The word may appear in casual conversations, historical documents, and informal writing in both regions.
Does Ditto Change in British English?
No. The spelling remains ditto in British, American, Canadian, and Australian English.
Regional differences may affect how often people use the word, but the spelling stays the same.
Is Ditto Suitable for Formal Writing?
Ditto is a standard English word, but it is often more natural in informal communication.
In academic, legal, or professional writing, repeating the information may be clearer than using ditto.
For example:
Less clear:
The same rule applies to the second section. Ditto for the third.
Clearer:
The same rule applies to the second and third sections.
The best choice depends on your audience and the context.
Which Version Should You Use?
Always use ditto when you mean “the same,” “me too,” or “I agree.”
Here is a practical guide for different regions and writing situations.
In Casual Conversations
Ditto is a natural way to agree with a friend.
“I cannot wait for the weekend.”

This sounds friendly and relaxed.
In Academic Writing
Academic writing usually requires clear explanations. Instead of using ditto, repeat the information or use a specific reference.
Example:
The first experiment produced positive results. The second experiment produced similar results.
This is clearer than using ditto without explaining what it refers to.
In Business Writing
You may use ditto in informal workplace messages when everyone understands the reference.
Example:
“The same deadline applies to the second project. Ditto for the third.”
For important instructions, it is better to state the details clearly.
