Many writers get confused between “enquiry” and “inquiry.” Both look correct. Both are used in English. But they are not always the same. This small difference often creates big confusion in emails, school writing, business communication, and even online searches.

This article will clear every doubt. You will learn the exact meaning, origin, spelling rules, real examples, common mistakes, and when to use each form. By the end, you will confidently choose the correct spelling in any situation without hesitation.

The Origin of Enquiry or Inquiry
Both words come from the same Latin root:
- Latin: inquirere → “to seek into” or “to ask”
- Old French: enquerre / enquerir
- Middle English: enqueren / inquiren
Over time, English developed two spellings:
- Enquiry → older British spelling form
- Inquiry → Latin-influenced, later standardized in American English
The difference is not about meaning. It is about language evolution and regional preference. British English kept both forms. American English simplified it to one standard spelling.
