peaceable

the word 'peaceable' is a direct descendant of the anglo-norman and middle english 'pesible', which itself evolved from the latin 'pacificus', meaning peace-making. the core morpheme 'peace' originates from the latin 'pax, pac-', denoting a state of tranquility, freedom from war, or a formal agreement to end hostilities. the suffix '-able', of latin origin via old french, attaches to nouns to form adjectives indicating a quality or tendency. thus, the literal construction 'peace + able' yields the meaning 'having the quality of peace' or 'inclined towards peace', a sense that has remained remarkably stable from its medieval origins to its modern usage describing a person's temperament or a calm situation.

Structure: peace (noun) + able (adjective suffix) peace (from latin 'pax, pac-', meaning peace, a treaty) + able (from latin '-abilis', a suffix forming adjectives meaning 'capable of, fit for, tending to').
