Morphology
unrelievable = relievable (semi-transparent) = un + relieve + able
Morphologically regular, but the sense relating to relieving someone from duty or providing a substitute is a specific usage that some learners may not immediately infer.
Etymology
The word unrelievable joins un- 'not' and relieve 'to take someone's place or free them from duty', like when a guard receives relief, so it means a person or post that cannot be replaced or freed.
