Capable of being appeased or satisfied; able to be calmed down or made content by some action or concession.
From 'appease' (to calm or satisfy) plus the suffix '-able' (capable of being). 'Appease' comes from Old French 'apaisier,' meaning to make peace, from 'a-' (to) and 'paisier' (to pacify), ultimately from Latin 'pax' (peace).
The opposite of 'appeasable' is crucial in history—Hitler was famously believed to be non-appeasable by British leaders, but only in hindsight. The word captures something psychologically important: whether someone can be satisfied or whether they'll always want more.
