expendable

the word "expendable" is built upon the verb "expend," which originates from the latin 'expendere', a compound of 'ex-' (out) and 'pendere' (to weigh, pay). this root evokes the ancient practice of weighing out money or resources. the suffix '-able', of latin origin, attaches to verbs to create adjectives meaning "capable of being [verbed]." therefore, the literal morphemic construction yields "capable of being paid out or used up." over time, this evolved from a purely financial sense to a broader meaning, first applied to military matériel designed to be consumed in use, and later to people or things considered acceptable or necessary to sacrifice for a larger objective.

Structure: expend + able expend (from latin 'expendere', meaning 'to weigh out, pay out'); able (from latin '-abilis', an adjective-forming suffix meaning 'capable of, fit for')
