:While a small minority will argue with this, since AD&D; 2nd Edition came out in 1989, almost everyone uses these terms the way you say, to refer to the various editions of the AD&D; family, completely ignoring the original D&D; and basic D&D.; Most people find it easier, whether or not they think it's strictly correct, to just agree that (in particular) "Second Editon" should refer to the version that says Second Edition on the cover in freaking inch-high letters, not to something else.
