WHAT IS THE DIFFERENCE BETWEEN WHETHER AND IF? CAN SOMEONE HELP ME?
Use "whether" when you could write it with "or not."
We'll go on the picnic whether it rains or not.
Use "if" when you can have a "then." If it doesn't rain, then we'll go on a picnic.
The truth is, though, people use "if" in place of "whether" all the time.
