If you are wondering whether the correct spelling is inquiry or enquiry, the answer depends mainly on the variety of English you are using. Both spellings are correct, but they are used differently in American and British English.
In general, inquiry is the preferred spelling in American English, where it covers both a simple question and a formal investigation. In British English, enquiry is commonly used for an ordinary request for information, while inquiry is often reserved for a formal investigation. Modern usage varies, and this distinction is not followed the same way by every writer or organization.
If you are comparing inquiry vs enquiry, enquiry vs inquiry, or wondering about the plural form enquiries, this guide explains the differences clearly.
Quick Answer: Inquiry or Enquiry?
| Word | Common Usage | Meaning |
| Inquiry | Mainly American English | A question, request for information, or investigation |
| Enquiry | Mainly British English | A question or request for information |
| Inquiry | Also British English | Often associated with a formal investigation |
| Enquiries | Plural of enquiry | Multiple questions or requests |
Short answer: Use inquiry in American English. In British English, enquiry is common for ordinary questions, while inquiry is often preferred for formal investigations.
Inquiry vs Enquiry: Regional and Contextual Differences
Both inquiry and enquiry are correct spellings, and the best choice depends on your audience.
In American English, inquiry covers both meanings:
- We received an inquiry about our services.
- The committee opened an inquiry into the matter.
The spelling enquiry is unusual in standard American writing. Because inquiry is such a strong convention in the US, many American editors, teachers, and style guides regard enquiry as a spelling mistake in American-context writing — though it remains a valid English word, particularly in British usage. This is a strong regional convention rather than an absolute grammar rule.
In British English, some traditional style conventions distinguish the two spellings by meaning rather than just region:
Enquiry is often used for an ordinary question or request for information.
- She made an enquiry about the opening hours.
- Please send all enquiries to our customer service team.
Inquiry is often used for a more formal investigation.
- An official inquiry was launched into the accident.
- The public inquiry examined the cause of the incident.
This distinction is useful but not absolute — modern British usage sometimes applies the two spellings more broadly, and individual publishers follow their own house style. The table below summarizes the pattern:
| English Variety | Preferred Spelling |
| American English | Inquiry (for both meanings) |
| British English (general question) | Enquiry |
| British English (formal investigation) | Inquiry |
The most important thing is to remain consistent throughout your writing. If your website, article, or document is written primarily for an American audience, inquiry is usually the best choice.

What Does Inquiry Mean?
An inquiry is a question, request for information, or investigation.
- She sent an inquiry about the course. — a request for information.
- The government launched an inquiry into the incident. — a formal investigation.
This makes inquiry a flexible word whose exact meaning depends on context.
What Does Enquiry Mean?
An enquiry generally means a question or request for information.
- I made an enquiry about the price.
- The hotel responded to our enquiry.
This spelling is especially common in British English. Someone might make an enquiry about a product, university course, reservation, or job. The spelling is much less common in American English, where inquiry is generally preferred.
A simple memory rule for the traditional British distinction:
- Enquiry = asking for information
- Inquiry = formal investigation
In American English, inquiry would normally be used in both situations.
Inquiry in a Sentence
- The company received an inquiry from a potential customer.
- She sent an inquiry about the job opening.
- The police began an inquiry into the incident.
- Please contact us if you have any further inquiries.
The meaning depends on context — an inquiry may be a simple question or a serious investigation.
Enquiry in a Sentence
- She made an enquiry about the university course.
- The hotel received several enquiries about room availability.
- Please send your enquiries by email.
- He contacted the office to make an enquiry about his application.
These examples are especially natural in British English.
Enquiries or Inquiries?
Enquiries is the plural of enquiry, referring to more than one question or request for information.
| Spelling | Common Usage |
| Enquiries | Mainly British English |
| Inquiries | Mainly American English |
- British English: Please send all enquiries to the office.
- American English: Please send all inquiries to the office.
The meaning is essentially the same.
Inquiry as a Formal Investigation
- The government announced a public inquiry.
- An inquiry was conducted into the cause of the accident.
- The committee completed its inquiry last year.
In this context, inquiry suggests a structured investigation rather than a simple question — this is also why traditional British usage sometimes reserves inquiry for official matters and enquiry for ordinary requests.
Enquiry as a Request for Information
- I sent an enquiry to the university.
- They received an enquiry about the product.
- For further enquiries, please contact our office.
An enquiry may involve a request for clarification, pricing, services, or availability — particularly in British English.
Inquiry vs Enquiry in Business Writing
- An American company may write: For sales inquiries, contact our team.
- A British company may write: For sales enquiries, contact our team.
If your business writes for an international audience, choose one spelling style and use it consistently rather than switching between the two without reason.
The Verbs: Inquire or Enquire?
The same spelling difference appears in the related verbs.
- Inquire is preferred in American English: She called to inquire about the price.
- Enquire is common in British English: She called to enquire about the price.
The same pattern applies as with the nouns: American English usually prefers inquire and inquiry, while British English may use enquire and enquiry, especially for ordinary requests.
How Do You Spell Inquiry and Enquiry?
American spelling: I-N-Q-U-I-R-Y — plural: inquiries Examples: customer inquiry, sales inquiry, official inquiry
British spelling: E-N-Q-U-I-R-Y — plural: enquiries Examples: customer enquiry, general enquiry, further enquiries
Why Do Inquiry and Enquiry Have Different Spellings?
The two spellings developed through differences in English usage over time. Both forms are historically related to the verbs inquire and enquire, and American and British English eventually settled on different preferences — American English standardized on inquiry, while British English kept both forms, with some writers developing the general-question versus formal-investigation distinction.
The two words are also pronounced identically or nearly identically in natural speech. The first vowel is usually unstressed and reduced to a weak schwa sound, so pronunciation does not clearly distinguish inquiry from enquiry. Because they sound the same, pronunciation cannot tell you which spelling to use — the choice depends on spelling convention, regional usage, and, in British contexts, whether you mean an ordinary question or a formal investigation.
Common Mistakes With Inquiry and Enquiry
A common mistake is assuming one spelling is always wrong — both are correct English spellings.
Another is mixing styles in the same document:
- ❌ Please send all enquiries. We will answer every inquiry quickly.
- ✔ Please send all inquiries. We will answer every inquiry quickly. (American style)
- ✔ Please send all enquiries. We will answer every enquiry quickly. (British style)
A third mistake is treating the British question-versus-investigation distinction as an absolute rule — it’s a helpful convention, but modern usage isn’t always strictly separated.

How to Remember the Difference
- American English → inquiry
- British English → enquiry for questions, inquiry for formal investigations
Think first about your audience: if you’re writing for US readers, use inquiry. If following British English, enquiry suits ordinary requests, while inquiry suits official investigations.
Why Context Matters
- She made an enquiry about the course. — a request for information.
- The government launched an inquiry into the incident. — an official investigation.
Words such as customer, price, and booking often suggest an ordinary request. Words such as government, official, and investigation often suggest a formal inquiry.
Is Enquiry a Real Word?
Yes. Enquiry is a real and correct English word, particularly associated with British English, where it often refers to a question or request for information. It should not be considered universally incorrect simply because American English prefers inquiry — both forms are valid, though regional and editorial preferences affect which is best for a given audience.
