I don't know if this commenter had known of the 2006 edn of Allen and Greenough's New Latin Grammar when (s)he wrote:
Allen and Grenough is the standard traditional grammar, but like most Classics grammars, it was written well before the advent of modern linguistic theory, and thus is burdened with a fairly outdated grammatical apparatus. Most of the accidence is fine, excepting some of the historical material, but the book's syntactic description is less reliable, IMO.
What is the "fairly outdated grammatical apparatus" in Allen and Greenough's New Latin Grammar? What is not linguistic about it?
