Definition of "jargoneer"

‘How excellent a thing is sleep,’ sighed Sancho Panza; ‘it wraps a man round like a cloak’—an excellent example, by the way, of how to say a thing concretely: a Jargoneer would have said that ‘among the beneficent qualities of sleep its capacity for withdrawing the human consciousness from the contemplation of immediate circumstances may perhaps be accounted not the least remarkable.’ How vile a thing—shall we say?—is the abstract noun!

Partnering, along with its less irritating cousin "partnership", crops up all over the place, being equally useful to the lazy jargoneer and the lazy policy-maker. It has been said that there is no noun which cannot be verbed; in the same way, there is now nothing, concrete or abstract, which cannot be partnered.
