Let’s take a minute to look at some of the many meanings while can have.
As a conjunction, while can mean ‘at the same time as’.
While we were sleeping, it snowed!
We can swap the two clauses around, but notice the comma goes away.
It snowed while we were sleeping!
While can have the same meaning as ‘but’.
One of the twins is shy, while the other is outgoing.
And while, or whilst in more formal contexts, can also be used in the same way as ‘although’.
While I know that sugar is bad for me, I can never say no to dessert!
As a noun, while can mean ‘a length of time’ and, in the expression ‘worth your while’, it can mean ‘worth the time and effort used’. So, finally…
Even though we only had a short while together, we hope this lesson was worth your while.
