I don't have my DM's guide in front of me but..
There are many weapon abilities that come in normal, and super-sized flavor. Good, for instance, doesn't do anything special except bypass DR. Holy, on the other hand, includes Good, and does an extra 2d6 points of damage to evil creatures.
There's also Evil...Unholy
Lawful...Axiomatic
Chaotic...Anarchic
Good, Evil, Lawful, and Chaotic just bypass DR. Whereas their supersized versions (Holy, Unholy, Axiomatic, Anarchic) count as their lesser form AND do 2d6 extra damage.
