Once again, Zippy plays with English morphology. This time it's -ity day in Dingburg:
We get happyosity, based on happy, extended by the accented variant of unaccented -ous; and rapturosity, either similarly derived (from rapture) or based directly on rapturous. Both have been invented a few times by others:
Rapture w/Cilantro and Risotto: I've just renamed this delicious dish, still lingering in tastebud memory from Sunday dinner. Shrimp and scallops cooked in chili oil, garlic, and cilantro. Lemon risotto. Rapturosity, indeed. (link)
If you would like, I would more than happy, even approaching rapturosity, to invent more adjectives to describe you! (link)
Bugfixes, new toys, and all-round happyosity. (link)
Are Americans so preoccupied with unhappiness that the majority of us would rather watch a news program about suffering, than one about happyosity? (link) [Blog posting entitled "Multihappyologist: One who studies many, much happiness"]
Playful -(os)ity formations have attracted occasional attention here on Language Log, beginning with the Snickers nougatocity coining here. This one, with the extension of the base, has an unusual spelling, with C rather than S. Following right on my nougaticity posting came Ben Zimmer on the example that probably started the playful -ity fashion, the noun bogosity, built on the slangy adjective bogus, treated as if it had the adjective suffix -ous.
Then followed seriosity in a Get Fuzzy cartoon, in a posting that also mentioned furiosity and fabulosity. All three are straightforwardly based on adjectives with the suffix -ous. They stand out because the suffix -ity isn't really productive (though there are models like curiosity).
Finally came a Zippy, with the extended noun randomosity, based on random. And now we can experience morphological happyosity and rapturosity again.
