Enquiry or Inquiry – Quick Answer
Quick Answer:
- Inquiry → Mostly used in American English. Refers to an official investigation or formal question.
- Enquiry → Mostly used in British English. Often refers to a general question or request for information.
Examples:
- American English: “The police opened an inquiry into the theft.”
- British English: “I made an enquiry about the train schedule.”
Tip: In casual British English, enquiry is more common; in formal or legal contexts, inquiry is often preferred.
The Origin of Enquiry and Inquiry
Both words stem from the Latin word “inquirere,” meaning “to seek for” or “to ask.” Over time, English borrowed this term and developed two spellings:
- Inquiry → Standardized in American English.
- Enquiry → Retained in British English, keeping the “e” prefix.
The distinction between the two became more pronounced in the 19th century as American English developed its own conventions. Today, the difference is largely regional rather than semantic, though formal contexts sometimes favor inquiry regardless of region.
