Why this word is great
EXPOSTULATE — [Verb] To reason earnestly with someone in an effort to dissuade or protest against a particular course of action. From the Latin expostulare ("to demand urgently, remonstrate"), from ex- ("thoroughly") and postulare ("to demand"). Unlike "remonstrate," which carries the sting of formal indignation, or "dissuade," which merely names the intended outcome, to expostulate is the patient, logical, and thorough laying-out of a case. It is a friend's low, urgent voice over a third drink, the measured cadence of a parent explaining consequence for the hundredth time, the quiet, desperate clarity of one last appeal before the door clicks shut. One argues with the cliff's edge, politely.
