If you’ve ever written “inquire” and wondered whether “enquire” might be the correct spelling, you’re not alone. Both words appear in dictionaries, professional writing, websites, and everyday conversations. The confusion usually comes from the fact that English has developed different spelling preferences across regions.
The good news is simple: both “inquire” and “enquire” are legitimate English words. The choice usually depends on the variety of English you’re using and, in some British contexts, the meaning you intend.
For American English, inquire is the standard spelling. British English commonly uses enquire for ordinary requests for information, although inquire also remains established, particularly when referring to a formal investigation. Other English varieties can show both forms as well.
That distinction matters when you’re writing for a particular audience. A US business email might say, “I’m writing to inquire about your services.” A British company might naturally write, “I’m writing to enquire about your services.” Neither sentence contains a spelling error.
Quick Answer
Inquire and enquire are both correct spellings. In US English, inquire is the normal and preferred form. In British English, enquire is common for asking for information, while inquire is also used, especially for formal investigations.
For example:
- US English: I called to inquire about the available courses.
- British English: I called to enquire about the available courses.
- Formal investigation: The committee will inquire into the allegations.
So, if you’re writing specifically for an American audience, choose inquire. If you’re following British English conventions, enquire may be appropriate for a general request.
Comparison Overview
The difference between inquire and enquire is mainly regional, although British usage can add a distinction based on meaning. Both words function as verbs and can describe the act of seeking information.
| Feature | Inquire | Enquire |
| Part of speech | Verb | Verb |
| Basic meaning | Ask for information; investigate | Ask for information; investigate |
| US English | Standard and preferred | Uncommon |
| British English | Used | Common |
| Formal investigation | Common | Less typical |
| Related noun | Inquiry | Enquiry |
| US plural | Inquiries | — |
| British plural | Inquiries | Enquiries |
| Example | I called to inquire about the price. | I called to enquire about the price. |
The important point is that “enquire” isn’t simply a misspelling of “inquire.” It has a legitimate history and established usage.
Likewise, “inquire” isn’t an American-only invention. It has a long history in English and remains a standard word across multiple varieties of the language.
Main Differences Between Inquire or Enquire
The clearest difference appears when you compare American and British English. American English generally favors inquire, while British English permits both inquire and enquire.
There’s also a traditional British distinction between the two forms. In that pattern, enquire refers to asking for information, while inquire can refer to conducting an investigation.
However, real-world British usage isn’t perfectly divided along those lines. You may find enquire used broadly, while inquire appears in contexts that don’t involve a formal investigation. Style guides and individual organizations can also make different choices.
Inquire in American English
In American English, inquire is the normal spelling for both general questions and investigations.
You might use it when asking about:
- A product
- A job opening
- A university course
- A reservation
- A price
- A service
- An application
- A formal investigation
For example:
I’d like to inquire about the position.
Here, inquire simply means ask for information.
You can also use it in a more formal context:
The agency will inquire into the circumstances surrounding the incident.
The same spelling works in both situations. American English doesn’t generally require you to switch from inquire to enquire when the context changes.
Enquire in British English
In British English, enquire is especially common when someone simply wants information.
For example:
I’m writing to enquire about your evening classes.
This usage is completely standard in British English.
You might also see enquire on British business websites, customer-service pages, advertisements, and formal correspondence.
A company could write:
Please contact us if you would like to enquire about our services.
That sentence sounds natural within British English conventions.
However, British English also uses inquire. The two forms aren’t separated by an absolute linguistic wall.
Inquire for Formal Investigation
One useful distinction appears in traditional British usage.
Inquire can mean to investigate something systematically or officially.
For example:
The committee will inquire into the cause of the accident.
Here, the verb suggests more than simply asking a question. It describes an investigation intended to establish facts.
This distinction explains why inquiry appears frequently in official contexts.
For example:
- A public inquiry was announced.
- The inquiry examined the circumstances.
- The committee conducted an inquiry.
In American English, inquiry also works for ordinary requests for information:
We received an inquiry about the new membership plan.
That broader American usage is one reason the distinction between inquiry and enquiry can seem confusing to international readers.
What Does “Inquire” Mean?
Inquire means to ask for information or investigate something.
The exact meaning depends on the surrounding words.
When you inquire about something, you normally want information.
She called to inquire about the delivery date.
When you inquire into something, the verb often suggests investigation.
The board decided to inquire into the complaint.
That small preposition can change the flavor of the sentence.
Common Uses of Inquire
You can use inquire when asking about:
- Prices
- Availability
- Requirements
- Schedules
- Services
- Employment opportunities
- Educational programs
- Policies
- Procedures
Examples:
- I’d like to inquire about your return policy.
- He called to inquire about the apartment.
- She inquired whether the meeting had been canceled.
- We received several inquiries about the new program.
The word often sounds slightly more formal than simply saying ask. That’s why it appears frequently in business and professional writing.
What Does “Enquire” Mean?
Enquire generally means to ask for information. It is especially associated with British English.
For example:
She called to enquire about the ticket prices.
The meaning is straightforward. She wants information about ticket prices.
You can also use it with different sentence structures:
- He enquired about the application process.
- They enquired whether the room was available.
- I’d like to enquire about your opening hours.
In American English, these sentences would normally use inquire instead.
Is Enquire a Real Word?
Yes. Enquire is a standard English word.
It isn’t an accidental variation created by a spelling mistake. It has a long history in English and remains established in dictionaries and British usage.
The fact that American English generally prefers inquire doesn’t make enquire incorrect.
Think of it like color and colour. Regional spelling preferences don’t automatically turn one form into an error.
Inquire vs. Enquire in American English
If your article, email, school assignment, website, or business communication follows US English, inquire is the safest and most consistent choice.
American English normally uses:
- inquire
- inquiry
- inquiries
Examples:
Customers can inquire about their orders by phone.
We received an inquiry from a potential client.
The company received hundreds of inquiries after the announcement.
The spelling enquire can appear in American writing, especially when quoting British material or referring to a British organization. However, it isn’t the normal American spelling.
Why Americans Prefer “Inquire”
American English generally standardized around inquire as the dominant form. Over time, that spelling became conventional in American dictionaries, publishing, education, and professional communication.
As a result, an American reader will usually recognize enquire immediately. It may simply look distinctly British.
That doesn’t mean the word becomes meaningless or incorrect. It reflects a different regional convention.
Inquire vs. Enquire in British English
British English is more flexible.
You can find both enquire and inquire in British writing. The traditional distinction often looks like this:
| Meaning | Traditional British preference |
| Ask for information | Enquire |
| Investigate formally | Inquire |
| General request | Enquire |
| Official investigation | Inquire |
For example:
I’d like to enquire about the cost.
But:
The commission will inquire into the matter.
This distinction is useful, but don’t treat it as an ironclad rule. Modern British usage includes plenty of overlap.
Different institutions may also follow different editorial preferences.
Inquire vs. Enquire: Meaning and Usage Differences
The words overlap heavily in meaning. The main differences involve regional preference and traditional British usage.
Inquire Can Mean “Ask”
I called to inquire about the schedule.
Here, no formal investigation is involved.
Inquire Can Mean “Investigate”
The committee will inquire into the allegations.
The second sentence suggests a structured examination of facts.
Enquire Usually Means “Ask”
She stopped at the desk to enquire about the next train.
This is a straightforward request for information.
The crucial takeaway is that the spelling alone doesn’t always tell you exactly what the writer means. Context matters.
Inquiry vs. Enquiry: What Is the Correct Noun?
The noun forms create another layer of confusion.
American English generally uses inquiry:
I sent an inquiry about the course.
British English commonly uses enquiry for ordinary requests:
I sent an enquiry about the course.
British English also uses inquiry in formal investigative contexts.
For example:
The public inquiry examined the circumstances surrounding the incident.
This distinction is worth remembering because the noun often follows the same regional pattern as the verb.
Inquiry and Enquiry Plurals
The plural forms are:
- inquiry → inquiries
- enquiry → enquiries
Notice what happens to the final y.
The y changes to ie before the plural s.
Examples:
- one inquiry → two inquiries
- one enquiry → two enquiries

Inquire, Enquire, Inquiry, and Enquiry Word Family
These four forms are closely related but aren’t interchangeable in every regional context.
| Verb | Noun | Example |
| Inquire | Inquiry | I will inquire about the course. |
| Enquire | Enquiry | I will enquire about the course. |
| Inquire | Inquiry | The agency launched an inquiry. |
| Enquire | Enquiry | She made an enquiry by email. |
For American writing, inquire/inquiry provides the most consistent pair.
For British writing, you may encounter either family depending on context and editorial style.

Common Mistakes With Inquire and Enquire
Several mistakes appear because writers treat regional spelling as a simple right-or-wrong issue.
Mistake: Calling “Enquire” Incorrect
Enquire is not inherently incorrect.
It is a recognized English spelling, particularly in British usage.
Mistake: Assuming “Inquire” Means Only Investigate
In American English, inquire commonly means simply ask for information.
I called to inquire about the price.
No investigation is happening there.
Mistake: Treating the British Distinction as Absolute
The traditional British distinction can help explain usage, but modern British English doesn’t always follow it rigidly.
You’ll find inquire and enquire in overlapping contexts.
Mistake: Mixing Regional Styles
A document that otherwise follows American spelling might suddenly use enquire.
That isn’t necessarily grammatically wrong. Still, inconsistent regional spelling can make professional writing look less polished.
Inquire or Enquire for Business and Professional Writing?
Your audience should guide the choice.
If you’re writing for an American company, customer base, or publication, inquire is usually the natural choice.
For example:
Please contact our support team to inquire about your order.
For a British audience, enquire may sound more natural:
Please contact our support team to enquire about your order.
Neither sentence changes the underlying message.
A Practical Business Rule
Use this simple approach:
- US audience: Use inquire.
- UK audience: Consider enquire for ordinary requests.
- Formal UK investigation: Inquire may be preferred.
- International audience: Choose one regional style and use it consistently.
- Company style guide: Follow the organization’s established spelling.
Consistency is often more important than forcing one spelling onto every English-speaking audience.
