10 Years After

Generally Never
I've had the discussion several times, with several people, about very unique. I don't see a problem with the phrase. Sure, it's redundant and technically incorrect. My point is, I can see where it is useful hyperbole. (It's even in most dictionaries!) However, my Spanish book uses, while giving some rule of Spanish grammar, the phrase generally never!
This is isn't exageration, it's contradiction. If generally means "more often than not" and never means "does not" then the phrase makes no sense. Either it happens more often than not or it does not happen, the two are mutually exclusive. Generally implies that this rule is not always followed, but is most of the time. Never means that the rule is absolute.

Or am I wrong?
