What does expendable mean?
Expendable is an adjective describing something — or, more chillingly, someone — considered to be of such limited value that it can be used up, sacrificed, or simply done away with when no longer needed. In practical contexts the word is neutral: militaries speak of expendable supplies and rockets carry expendable stages that are jettisoned after use. But when applied to people, as in calling workers expendable, it becomes harshly pejorative, implying that lives or careers matter less than efficiency or profit. The word derives from the verb expend, meaning to spend or use up, ultimately from Latin expendere, to weigh out or pay. Its close relatives include expense and expenditure. Because the word captures both mundane disposal and moral disregard, it is especially useful in discussions of economics, warfare, ethics, and labor — wherever value and sacrifice intersect.
Able to be sacrificed, discarded, or done without because it is regarded as having little value or importance.
"The general viewed the outpost as expendable and ordered a retreat."
Applied to people, the term is strongly negative and dehumanizing.
(Of equipment or supplies) designed to be used once and then discarded or consumed in operation.
"The spacecraft carried both reusable instruments and expendable boosters."
Neutral register in military and aerospace contexts.
An expendable person or thing; usually used in the plural ('the expendables') to refer to people regarded as dispensable.
"To the corporation, the temporary contractors were merely expendables."
Much rarer than the adjective; typically appears in the plural.
Used only when 'expendable' functions as a noun, referring collectively to people or items considered dispensable. As an adjective, it does not inflect for number.
"The regime treated its soldiers as expendables, sending wave after wave into battle."
In the film 'The Expendables', the name is ironic — these action heroes are anything but easy to get rid of.

Etymology of expendable
Expendable derives from the verb expend, which entered English in the early 17th century from Latin expendere, meaning to weigh out or pay money. The Latin root combines ex- (out) with pendere (to hang, weigh, or pay). The adjective form followed shortly afterward, first in the literal financial sense of something that could be spent, later extending to its modern meanings of discardable or dispensable. Cognates sharing this Latin root include expense, expenditure, compensate, and pension.
