Usage

What's the difference between inquiry and enquiry? Inquiry and enquiry have the same meanings: a question, an investigation, a request for information, or the process of seeking information. Enquiry is a less common variant of inquiry. Their verb forms—inquire and enquire—also mean the same thing: to ask, to seek information, or to investigate. Both inquiry and enquiry are somewhat formal, especially compared to similar terms like question or investigation. Some speakers of British English may use both words, preferring inquiry in contexts that are more formal. In the U. S., enquiry is rarely used. Here’s an example of inquiry used correctly in a sentence. Example: I forwarded you an email with an inquiry about the open position. Enquiry could be used in this sentence in the same exact way. Most of these same distinctions apply to the verbs inquire and enquire. To learn more about them, read the full breakdown of the difference between inquire and enquire.

Etymology

Origin of inquiry

First recorded in 1400–50; inquire + -y ³; replacing late Middle English enquery

Explanation

When you ask the guy behind the counter if they've got any aspirin, you're making an inquiry. Almost any search for information or knowledge is an inquiry, though an inquiry is often an official search. Though any question is, technically, an inquiry, that word is usually used to refer to an official or public search for the truth. For instance, after a plane crash, the government launches an inquiry into the cause. Politicians and government officials are often the ones who demand an inquiry when an important question needs to be answered, but a child can do the same thing. If your kid wants to know what's for dinner, she can make an inquiry about it. She can also just, y'know, ask.
