I would be willing to bet you could find another reference which
would not make this distinction without a great deal of
difficulty. There are really not that many cases in English
where words have really precise meaning.

I strongly believe the rules for correct English are more arcane
than the rules for Mathematica. But, a large amount of meaning
in English is context which allows useful communication to take
place when strict rules aren't followed. In fact, the lack of
precision in English is what makes it difficult to create
something like Wolfram Alpha and makes Wolfram Alpha so impressive.
