On alieniloquent, alieniloquence, alieniloquacious, alieniloquy, alieniloquist, alieniloquacious, et alios

Per Oxford Dictionaries Online, an alieniloquy is

an instance of straying from the subject one is supposed to be talking about; rambling of evasive talk”.

Aliens are “others”, of course, this this is talking about other things if you would. It derives from

post-classical Latin alieniloquium allegory from classical Latin aliēnus + ‑loquium, after Hellenistic Greek ἀλληγορία.

Since all nouns ending in -iloquy have corresponding derived adjectives ending in ‑iloquent, the world you’re looking for is therefore necessarily alieniloquent, pronounced /ˌeɪlɪəˈnɪləkwənt/.

Unless of course you prefer a term a tad less...grandiloquent? :-)
