the word survivability is a modern formation, constructed within english by combining the established verb 'survive' with the productive noun suffix '-ability'. the core root, 'survive', originates from the latin 'supervivere', literally 'to live over or beyond' a threat or event. this latin term itself is built from 'vivere', the verb 'to live', a root tracing back to the proto-indo-European gʷíh₃weti, source of vital terms related to life. the suffix '-ability', indicating a capacity or quality, descends from latin '-abilitas'. thus, survivability logically denotes 'the quality or capacity of living beyond' challenging circumstances, a meaning that has expanded from biological contexts to include technological and systemic endurance.

Structure: surviv(e) (to live through) + ability (capacity or quality) - surviv(e): from latin 'supervivere', meaning 'to outlive, live beyond', composed of 'super-' (over, beyond) and 'vivere' (to live). in this word, it functions as the verb root meaning 'to remain alive'. - ability: from latin '-abilitas', a suffix forming nouns of quality from adjectives ending in '-abilis' (able to be). it functions as a noun-forming suffix meaning 'the quality or state of being able'.
