- A conjunction
- A noun
As a conjunction, it connects two clauses.

What Does Whilst Mean?
Definition of Whilst
Whilst is a conjunction that has virtually the same meaning as while. It means during the time that, at the same time as, or sometimes although.
Unlike while, whilst is mostly associated with British English and often gives writing a slightly more formal, literary, or old-fashioned tone.
Importantly, whilst is not more grammatically correct than while. The two words are interchangeable in most contexts, but they differ in style and regional preference.
Origin of Whilst
The word whilst developed in Middle English as a variation of while, with the addition of the suffix -st, which also appeared in older English words such as amongst and amidst.
Over time, while became the dominant form in most English-speaking countries, while whilst remained in use mainly in Britain and some Commonwealth nations.
Grammar of Whilst
Like while, whilst functions as a conjunction.
Examples:
- She read a novel whilst waiting for the train.
- He listened carefully whilst taking notes.
- Whilst I understand your concern, I believe another solution is better.
There is no grammatical difference between while and whilst. The choice is based on style, audience, and regional usage—not grammar.
Pronunciation
Whilst
IPA: /waɪlst/
The final “st” sound distinguishes it from while and gives it a slightly more traditional rhythm in speech.
When to Use Whilst
Use whilst when:
- Writing primarily for a British audience.
- Adopting a formal or literary tone.
- Following an organization’s preferred style in the UK.
- Writing historical, legal, or traditional content where whilst sounds natural.
Avoid using whilst simply because it seems more sophisticated. In many contexts, especially outside the UK, it can sound unnecessarily formal or dated.

Professional Use
In the United Kingdom, whilst sometimes appears in:
- Legal documents
- Government publications
- Academic papers
- Policy documents
- Traditional business correspondence
Examples:
- Applicants must remain seated whilst the examination is in progress.
- Employees should wear protective equipment whilst operating machinery.
- Please retain this document whilst your application is being processed.
Although these examples are perfectly correct, many organizations now prefer while because it is shorter and more familiar to international readers.
Academic Use
British universities generally accept both while and whilst. However, consistency matters more than the choice itself.
For example:
✔ While analyzing the results, researchers identified several trends.
✔ Whilst analyzing the results, researchers identified several trends.
Both sentences are correct. The key is not to switch between the two forms without a reason.

Examples:
- I’ll make dinner whilst you set the table.
- Can you wait here whilst I speak to the manager?
- She smiled whilst reading the letter.
- He fell asleep whilst watching television.
Outside the UK, these sentences would usually use while instead.
