Sort of, sort of not. It happens that sometimes you can't tell that the
precondition is violated until sometime late in the function. So it may
be a surprising place to see the word "precondition," but it still can
be a precondition check.

It *is* a synonym for "jargon," which is neither a good nor a bad thing.
Jargon exists for a reason: to allow us to communicate precisely about
topics in specialized domains. Can you imagine where we'd be if doctors
couldn't use medical jargon to describe symptoms and procedures?
