What is the difference between (if) and (whether) as ((adverb connectors))?
I need some examples, differences in meaning and use.
Let's find out whether/if she can go.
He began to doubt whether/if there was a God.
I want to know whether/if I can start work on Monday.
In other uses, they cannot be interchanged.
He didn't know whether to run or fight. (introduces two alternatives)
Obviously, we use "if" for conditionals, but you know that.
