When would one use the word whilst as opposed to using while?

"Whilst" and "while" are both conjunctions that mean "at the same time" or "during the time that." However, "whilst" is considered more formal and is primarily used in British English.

Here's a breakdown:

"Whilst"

* Formal: Used in more formal writing and speech, such as academic papers, legal documents, and formal speeches.

* British English: Primarily used in British English, although it can sometimes be found in American English.

"While"

* Informal: Used in everyday conversation and informal writing.

* Both British and American English: Widely used in both varieties of English.

Example:

* Formal: "Whilst I was working on the project, I noticed a discrepancy in the data."

* Informal: "While I was working on the project, I noticed a discrepancy in the data."

In summary:

Use "while" in most situations. Use "whilst" if you want to sound more formal or if you are writing in British English.
