It should be noted that classic D&D names like Greyhawk, Blackmarsh, Dragonlance and Ravenloft all follow this apparently '4E' compound naming convention.
It should also be noted that, if translated from their Latin/pseudo-Latin/Latinized Greek forms into English, many of the 'proper' scientific names for dinosaurs (terriblelizards) are more of the same as well. Tyrantlizard kings, Three-hornedfaces, Roofedlizards, thunderlizards/deceptivelizards …
Compound naming, especially for people, is a much older thing than D&D...or even Latin and Greek. Apparently compound names are an Indo-European thing, which may see it back several thousand years. (see this wikipedia article's section on names)...although honestly, don't other language families do this as well? I can't say I personally speak any non-Indo-European langages...anybody out there speak Japanese or Chinese or something else "exotic"? Do they do this as well? Maybe its a deeper human thing?
I don't mind it as such. But somewhere along the line, between 4e and Magic cards, it became obvious that WotC was using it as a technique for easily generating IP-stampable names rather than for artistic or coolness purposes.
