The whole thing boils down to the difference between "normal" and
"exceptional". FWIW, here is how I explain it in my courses:

A program is basically looping (if it were to do things just once, it
would be faster by hand than writing a program). The loop is the general
case, the "rule". Sometimes, you encounter a condition that cannot be
handled by the normal "rule" and requires a different treatement: it is
an "exception" to the rule. That's why it's called exception, and not
trap, abnormality, failure...
