Etymology
the word lethality is a modern english formation, built upon the adjective 'lethal' with the addition of the noun-forming suffix '-ity'. the core root, 'lethal', traces back to latin letalis, meaning 'deadly' or 'fatal', which itself is derived from letum, a poetic term for 'death'. the suffix '-ity' entered english via old french from latin -itas, a common means of abstracting a quality from an adjective. therefore, lethality literally means 'the state or quality of being deadly', a direct and logical evolution from its classical components to its contemporary usage in contexts ranging from medicine to military science.
