Want to shut up quarry every so often (6)
I believe the answer is:
penury
'want' is the definition.
(thesaurus)
'shut up quarry every so often' is the wordplay.
'shut up' becomes 'pen' (pen can mean to shut in or enclose).
'every so often' means one should take alternating letters.
The alternate letters of 'quarry' are 'ury'.
'pen'+'ury'='PENURY'
'to' acts as a link.
(Other definitions for penury that I've seen before include "privation" , "Indigence, destitution" , "Extreme poverty or indigence" , "Real poverty" , "State of extreme poverty" .)
