dissuasion (n.)

early 15c., dissuasioun, "advice or exhortation in opposition to something," from Old French dissuasion (14c.) and directly from Latin dissuasionem (nominative dissuasio) "an advice to the contrary," noun of action from past-participle stem of dissuadere "to advise against, oppose by argument," from dis- "off, against" (see dis-) + suadere "to urge, incite, promote, advise, persuade," literally "recommend as good" (related to suavis "sweet"), from PIE root *swād- "sweet, pleasant" (see sweet (adj.)).
