Inquiry vs. Enquiry

Inquiry and enquiry are two of the most commonly confused words in English. They have almost identical meanings and come from similar root words but understanding the subtlety of the differences between inquiry and enquiry is important and will make your writing look more elegant. Basically, enquiry and inquiry mean investigation, but the words are used in difference contexts.

The difference between inquiry and enquiry

Inquiry is a noun, which means the act of asking for information or an official investigation. It is related to the verb inquire, which means to ask someone for information or to investigate.

• I called the doctor to inquire about my blood test results.
• Congress launched an inquiry into money laundering by major banks.
• The detective promised he would make some inquiries into the robberies.

So far, that’s quite easy to understand. But here’s where it gets confusing: In British English, you will come across words enquiry and enquire. Basically, they have the same meaning as inquiry and inquire, but they are used in different contexts. In British English, inquiry means a formal investigation, of the type carried out by government, police, scientists or an official organization. Enquiry has the same meaning, but it is reserved for less formal investigations. For example, you might see an enquiry desk at a library, or you might make an enquiry (ask) if someone is feeling well. The same rule applies for the verbs inquire and enquire. You use inquire for formal investigations, whereas enquire is used for less formal investigations. So, in formal situations use inquiry and inquire:

• The Levinson Inquiry transformed the editorial policies of British newspapers.
• Police soon arrived in the area, making inquiries as to what occurred the night before.
• We contacted the university to inquire about the poor exam results over the semester.
• During the interview, the panel inquired about my previous experience.

In less formal situations use enquiry and enquire:

• I’d like to make an enquiry about the flight times at the airport.
• May I enquire about the vegetarian options on your menu?
• If you get lost, look for the signs that point to the enquiry desk.
• For general enquiries, please contact the staff at reception.

Please remember that the difference between inquiry and enquiry only really matters in British English. In American English, inquiry is preferred as a synonym for investigations in all situations and enquiry is rarely used

When to use inquiry?

Use the word inquiry in American English as a synonym for investigation or the act of asking a question. Use Inquiry in British English as a synonym for a formal investigation.

Examples of inquiry

When to use enquiry?

Enquiry was widely used in British English as a synonym for investigation up until the start of the 20^th century. Technically, it is not incorrect to use it in the same way, but inquiry has become the preferred word.

Examples of enquiry
