whilst and while

Bothe while and whilst have been inthe language for avery long time.while was in use in old english.

Whilst is a middle english development of while.As conjuctions they are interchangeeable in meaning,but whilst has not survived in standard american english.

For ex:

I waited while breakfast was finished.
I waited whilst mugabe delivered what he thought were his pearls of wisdom.

This is well explained . thank you sasikanth.The examples are cleared my doubt more clearly

Once again no need of thanks to me for explaining you i also learned about this.

I have a doubt if whilst is the latest word for while then why it is not used frequently

I was confused regarding the usage of while and whilst. I will remember the explanation of Sasikanth.

I have a doubt if whilst is the latest word for while then why it is not used frequently

whilst is not at all popular among the people.hence it is not used more.

Actually 'while' is older than 'whilst' and both words are still used in British English and are interchangeable, just like 'although' and 'whereas'. Still, the only difference is in the usage of these two words, 'while' is used more commonly in speech whereas, 'whilst' is used mostly in literary compositions and is considered as a formal word.

I hope this helps.

Kalyaniji now I am confused with 'although' and 'whereas'. Kindly explain that.

Thank you kalyani for your detail explanation. I am waiting for your explanation which is asked by Devyani
