Inquiries and enquiries are both correct spellings, but they are mainly used in different varieties of English. Inquiries is the standard American English spelling, while enquiries is more common in British English and other varieties that follow British spelling.
Both forms refer to requests for information, questions, or attempts to find out more about something. The difference is mostly about spelling rather than meaning.
For example, an American company may write, “For further inquiries, please contact us.” A British company may write, “For further enquiries, please contact us.”
This spelling difference can be confusing because both words sound almost identical and have the same basic meaning. The choice usually depends on the English style you are following.
This guide explains the meaning, origin, British and American usage, common mistakes, examples, pronunciation, formal writing rules, and when to use each form.

| American English | British English |
| inquiry | enquiry |
| inquiries | enquiries |
In American English, inquiry is generally used for both a general request for information and a formal investigation.
In British English, enquiry is often used for a general request for information, while inquiry can be used for a formal investigation.
However, modern usage can vary, especially in different institutions and professional settings.
British English vs American English
This is primarily a British American spelling difference.
American English
American English normally uses:
inquiry
inquiries
Example:
We received several inquiries about the new service.
British English
British English commonly uses:
enquiry
enquiries
Example:
We received several enquiries about the new service.
In countries and organizations that follow British English, the second spelling is often preferred.
Which Spelling Should You Use?
The best choice depends on your audience.
Use “inquiries” when:
- You are writing in American English.
- Your audience is mainly in the United States.
- You are following an American style guide.
- Your organization uses American spelling.
Use “enquiries” when:
- You are writing in British English.
- Your audience is mainly in the United Kingdom.
- Your organization follows British spelling.
- You are following a British style guide.
For international writing, consistency matters more than switching between the two forms.
What About Pakistan?
English in Pakistan generally follows many British English conventions because of the country’s historical and educational connection with British English.
As a result, enquiries is often a natural choice in formal Pakistani writing.
However, American English is also widely encountered online, especially through websites, software, universities, and international companies.
The important point is to choose one style and use it consistently.
Inquiries vs Enquiries in Business Writing
Both forms are common in customer service and business communication.
American style
For product inquiries, please contact our support team.
British style
For product enquiries, please contact our support team.
Both sentences are grammatically correct.
The spelling should match the English variety used throughout the document.
Common Mistakes
1. Mixing spelling styles
A document may use enquiries in one section and inquiries in another without a reason.
This is not necessarily a serious grammar error, but it can make the writing look inconsistent.
2. Confusing the singular and plural
The singular forms are:
inquiry
enquiry
The plural forms are:
inquiries
enquiries
3. Thinking one form is always wrong
Neither spelling is universally wrong.
The difference mainly depends on regional English and, in some contexts, the distinction between a general question and a formal investigation.
4. Using “enquiries” in an American document
It may look unusual to an American audience because inquiries is the standard American form.

Inquiry vs Enquiry for Formal Investigations

In British English, inquiry can sometimes be preferred for a formal investigation, while enquiry can refer to a request for information.
For example:
Enquiry:
A customer asks about a product.
Inquiry:
A government body conducts a formal investigation.
This distinction is useful, but it is not absolute. Usage varies between organizations and English varieties.
American English generally uses inquiry for both meanings.

The difference is mainly visible in writing.
The first sound changes slightly in the spelling, but the words are close enough in pronunciation that context usually makes the meaning clear.
Singular and Plural Forms
| Singular | Plural |

Notice how the spelling changes in the plural.
The y becomes ies:

The English terms developed from French and Latin roots related to asking, seeking information, or investigating.
