Morphology

unexpendable = expendable (transparent) = un + expend + able

A standard negation (un-) applied to the adjective 'expendable' yields the straightforward meaning 'not able to be expended'.

Etymology

Unexpendable comes from un- 'not' and expend 'to use up', which is the same root as spend. So something unexpendable is 'not able to be used up' and is therefore essential.
