just for fun here's a sentence with 11 of those words: my fatuous and vacuous chicanery in pecuniary jejune only serve to inculcate me the quotidian need to abrogate the belie of ego--my circumlocutious lexicon aside.
Unfortunately, that isn't a sentence: "jejune" is an adjective, not a noun; "belie" is a verb, not a noun; "inculcate" takes an indirect object with "in", not a direct object. (Well, it does take a direct object, but it's the thing being inculcated, not the person it's being done to.)
