Difference Between: While vs. Whilst
In British English, while (hwaɪl) and whilst (hwaɪlst) mean the same thing when they are conjunctions (words that connect two ideas). As conjunctions, they can both mean ‘at the same time’ (e.g. Never do your homework while/whilst you watch TV) or ‘although/whereas’ (e.g. While/whilst it’s good to be out in the sun, we need to protect ourselves with sun cream). American English speakers never use whilst, and British English speakers only use it to be formal. In both British and American English, we can also use while as a verb or noun.
