In another newsgroup a discussion arose about the usage 'grammar errors' as opposed to 'grammatical errors'.
Googling the concurrence of the phrases (1750 web hits) shows a great many grammarians using both, often with 'grammar errors' in the title of books and other treatises.
Since I didn't find any discussion of the opposing usage on the aforementioned web hits, I thought I would be able to settle it by searching for the concurrence in this ng or alt.english.usage, but, not so.
Grammatical seems more 'proper', but grammar makes sense as well, as there are grammar books, grammar schools, grammar sites, and lots of other examples of 'grammar' being used as a adjective or as a part of a 'new' noun; or whatever you call that construction.
