Snark: not useful. And certainly not polite. I'd watch that stuff if I were you. The "truth" is, if there is such a thing as truth, which I gravely doubt, that your phrase "benefit of the doubt" definitely needed definition for the context. It still does. You should be able to define your own terms when asked! You know that. About palter and nexus: I have a rule of thumb about excessively abstruse vocabulary which has stood me in good stead. If by now I don't know that word (and I was an editor for years) ---- then the writer is posturing. And probably studied "Word of the Day" regularly for a long time. As an editor, I would say Keep It Simple. I do not add the usual clichéd ending because it doesn't apply to you.
