Inquire or Enquire: Which Spelling Should You Use?

Both inquire and enquire are correct. “Inquire” is preferred in American English, while “enquire” is more common in British English for general questions. In formal British usage, “inquire” may also refer to an official investigation.

Writers often pause when choosing between inquire and enquire. The words look slightly different, but they usually mean the same thing: to ask for information.

The main difference is regional preference. American English strongly prefers inquire, while British English uses both forms. Some British writers also make a small distinction between asking a normal question and carrying out a formal investigation. This guide explains the meanings, spellings, pronunciation, related nouns, and the best form to use for your audience.

What Is the Difference Between Inquire and Enquire?

Inquire and enquire both mean to ask for information, check something, or seek an answer.

The choice usually depends on the variety of English you are using:

• Inquire is standard in American English.
• Enquire is common in British English for ordinary questions.
• Inquire may be preferred in British English for formal investigations.
• Both spellings are understood internationally.

Word	Main Meaning	Preferred Region or Context	Example
Inquire	To ask for information	American English	I called to inquire about the price.
Enquire	To ask for information	British English	I called to enquire about the price.
Inquire	To investigate formally	Formal British usage	The committee will inquire into the complaint.

The difference is usually about spelling style rather than grammar.

What Does Inquire Mean?

It is the standard spelling in American English and is suitable for both casual and formal situations.

Examples:

• I am writing to inquire about the job opening.

• The customer inquired whether the item was available.
• We should inquire before making a decision.

• Base form: inquire

• Past tense: inquired
• Past participle: inquired
• Present participle: inquiring

Examples:

What Does Enquire Mean?

Enquire also means to ask for information. It is most commonly used in British English.

Examples:

• I would like to enquire about your opening hours.
• She enquired whether the room was available.
• Please enquire at the front desk.

Inquire or Enquire in British English

Enquire for General Questions

Enquire is often used for an ordinary request for information.

Inquire for Formal Investigations

Inquire may be used when an organization, committee, or authority investigates something carefully.

• A panel was formed to inquire into the failure.

This distinction is useful, but it is not followed by every British writer. Many dictionaries and publications treat inquire and enquire as spelling variants with the same basic meaning.

For consistent British writing, you may use enquire for everyday questions and inquire for official investigations.

Inquire or Enquire in American English

American English normally uses inquire in all situations.

The spelling enquire is understandable to American readers, but it is uncommon and may look British. For writing aimed at a US audience, inquire is the safest choice.

Common Mistakes

Incorrect or Inconsistent	Better Version	Why
I want to inquiry about the course.	I want to inquire about the course.	“Inquire” is the verb; “inquiry” is a noun.
She made an inquire about the price.	She made an inquiry about the price.	A request for information is an inquiry.
We received an enquire yesterday.	We received an enquiry yesterday.	Use the noun form after “an.”
Please enquire about the service. We welcome all inquiries.	Use either British or American forms consistently.	Mixed spelling can look careless.
The committee will inquire about the allegations.	The committee will inquire into the allegations.	“Inquire into” is clearer for a formal investigation.

Mistake 1: Confusing the Verb and Noun

Incorrect:

• I sent an inquire yesterday.

Correct:

• I sent an inquiry yesterday.

Use inquire as a verb and inquiry as a noun.

Mistake 2: Mixing Regional Spellings

Inconsistent:

• Please enquire using our online inquiry form.

Consistent British version:

• Please enquire using our online enquiry form.

Consistent American version:

• Please inquire using our online inquiry form.

Mixing forms is not always grammatically wrong, especially when making the British distinction between a question and an investigation. However, accidental mixing may make your writing look inconsistent.

Mistake 3: Assuming Enquire Is Incorrect

Enquire is not a spelling mistake. It is an accepted British English form.

However, it is less common in American English. American writers should normally use inquire.

A Simple Memory Tip

Remember:

• Enquire is often used in England.
• Inquire is used in the United States and for formal investigations.

This is only a memory aid, not a strict grammar rule. British English may use both spellings, while American English usually uses inquire.

Which Spelling Should You Use?

Use inquire when:

• You are writing in American English.
• Your audience is mainly in the United States.
• You are describing a formal investigation.
• You want one spelling that is widely accepted internationally.

Use enquire when:

• You are writing in British English.
• You are asking an ordinary question.
• Your organization uses “enquiry” in its house style.
• The rest of your content follows British spelling.

For formal, academic, or professional work, follow the required dictionary or style guide. Most importantly, keep your chosen spelling consistent.
