Agency you fear might finally provide shelter (4)
I believe the answer is:
yurt
'shelter' is the definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?
'agency you fear might finally' is the wordplay.
'finally' indicates one should take the final letters.
The final letters of 'agency you fear might' are 'YURT'.
'provide' is the link.
Can you help me to learn more?
(Other definitions for yurt that I've seen before include "Mongolian circular tent" , "Nomadic circular tent" .)
