Whilst vs. While: the Definition

What Does Whilst Mean?

Whilst often carries the same meaning as while, signifying a period of time in which something is happening. Its use is predominantly found in British English. It’s important to note that, while whilst is used as a conjunction or adverb, it is not used as a noun.

While describes a duration of time and is commonly utilized in both American and British English. It functions as a conjunction, noun, and verb. For example, as a noun, one might say, “It’s been a while since our last meeting”. As a conjunction, one could use while in a sentence like, “I read a book while I waited.”

Whilst vs. While: Usage and Examples

Whilst and while are familiar to many of us as they both function in similar ways within the English language. They are indeed often interchangeable, serving as conjunctions to indicate that two events are occurring simultaneously.


  • While is predominantly used in American English.
  • Whilst is more commonly used in British English, although it’s considered a bit formal or even archaic.

In both of these cases, while and whilst could be swapped without changing the meaning of the sentence. However, it’s important to consider your audience and the formality of the context when choosing which word to use.

Conjunction Use:

  • Both words can start a subordinate clause in a compound sentence.
    • Example: “While/Whilst I enjoy swimming, I don’t like getting sunburned.”

Adverbial Use:

  • As adverbs, they can mean ‘at the same time as’.

Remember, our choice between ‘while’ and ‘whilst’ can also be influenced by who we are talking to or writing for. When in doubt and in more formal writing, ‘while’ is generally the safer choice, especially in American English.

Tips to Remember the Difference
