The tendency for -ify words to be nouned as -ification doesn't really make a lot of sense if you think about it, because nouning them as -ifaction doesn't require sticking another suffix in the middle of the word, when the -ificate form isn't a valid form of the word.
@starkatt do they have different meanings?
@Felthry hm, now that I think about it a little more, I'm not actually certain.
@Felthry heh, this made me realize that "liquification" and "liquefaction" are both words, with different meanings :D
