Continuously and continually
Yes we know both words come from the root word " continue" , but they mean very different things.
Continuously means never ending.
Example :Hopefully your efforts of becoming successful are continuous, because you never want to stop improving in future.
Continual means whatever you're referring to stops and starts.
Example : just wondering when Jane and Israel will learn to get along, their Continual disagreements are becoming increasingly unbearable.
Example using both words in a sentence :
That's why you should focus on continuous improvement but
plan to have continual meetings with your accountant: The
former should never, ever stop, and the other (mercifully) should.
