How To Use Inquiry In A Sentence

How to Use "Inquiry" in a Sentence: Rules, Patterns, and 30+ Examples

Learning how to use inquiry in a sentence is easier than it looks once you understand that the word simply means a formal act of asking for information. Unlike the everyday word "question," inquiry carries a more official, structured, or investigative tone, which is why it appears constantly in academic writing, business emails, legal reports, and news articles. Mastering this word will instantly make your English sound more polished and professional.

What Does "Inquiry" Actually Mean?

Inquiry (also spelled enquiry in British English) is a noun with three closely related meanings:

• An act of asking for information — "The customer made an inquiry about delivery times."
• An official investigation — "Congress launched an inquiry into the data breach."
• A systematic search for knowledge — "Scientific inquiry begins with curiosity."

Notice that in every case, inquiry names the process, not the question itself. That distinction is the key to using it correctly.

The Basic Sentence Structures

You can place inquiry in almost any position a normal noun can occupy. Here are the five most common patterns:

1. Subject + verb + inquiry

• "She submitted an inquiry regarding the scholarship deadline."
• "The police opened an inquiry after the incident."

2. Inquiry + verb + complement

• "The inquiry revealed serious flaws in the safety report."
• "His inquiry went unanswered for two weeks."

3. Make / launch / open / conduct + an inquiry

• "We need to conduct an inquiry before signing the contract."
• "The university launched an inquiry into the professor's research."

4. Inquiry + about / into / regarding + topic

• "I'm writing in response to your inquiry about the rental property."
• "The committee's inquiry into the scandal lasted eight months."

5. Adjective + inquiry

• "Please direct all further inquiries to the main office."
• "She handled the difficult inquiry with great patience."

Choosing the Right Preposition

Prepositions are where most learners stumble. Follow these simple rules:

| Preposition | Use it when... " | | regarding / concerning | formal written reference | "Thank you for your inquiry regarding our services.Because of that, | Example | |---|---|---| | about | asking for general information | "He called with an inquiry about pricing. " | | into | investigating something deeply | "The inquiry into the accident is ongoing." | | from | identifying who asked | "We received an inquiry from a potential investor.

A helpful trick: use about for asking and into for investigating.
