To calm, soothe, or ease someone's pain, worry, or anger (archaic form of assuage).
From Latin 'assuadere' (to make pleasant), composed of 'ad-' (to) and 'suadere' (to persuade, advise). This is an obsolete or dialectal variant of the more common 'assuage.'
This is a beautiful, forgotten ancestor of 'assuage'—medieval and Elizabethan writers used it to describe the gentle, persuasive comfort someone offers when you're suffering, though modern English simplified it to just 'assuage.'
