Kind of key used in a case of staff shortage? (8)
I believe the answer is:
skeleton
I believe this is a triple definition!
'kind of key' is the first definition.
(I've seen this before)
'used in' acts as a link.
'a case' is the second definition.
(thesaurus)
'of' acts as a link.
'staff shortage?' is the third definition.
'skeleton' can be an answer for 'staff' (I have seen 'tiny staff' mean 'skeleton' so perhaps 'staff' could also mean 'skeleton'). I'm not sure about the 'shortage?' bit.
Can you help me to learn more?
(Other definitions for skeleton that I've seen before include "Kind of key" , "Basic scheme" , "Scheme reduced to its essential elements" , "one doesn't want found in cupboard" , "emaciated type" .)
