The short answer is simple:

The Origin of Enquiry or Inquiry
Both words come from the Old French word enquerre, which means “to seek” or “to ask.” This word later became the Latin-based English verb inquire.
Over time, English developed two spellings:
- Enquiry
- Inquiry
In earlier British English, many writers used both spellings for different meanings.
Traditionally:
- Enquiry meant asking a question or requesting information.
- Inquiry referred to a formal investigation.
Today, that distinction is less strict. Most dictionaries accept both spellings, although regional preferences remain.
