Affected - temporary shelter (4)
I believe the answer is:
camp
This clue is a double definition.
'affected' is the first definition.
(camp can mean exaggerated or affected)
'temporary shelter' is the second definition.
(I've seen this in another clue)
(Other definitions for camp that I've seen before include "Affected - group of tents" , "holiday location" , "Hill fort; extravagantly theatrical" , "Stay in tents" , "Temporary accommodation; exaggeratedly theatrical" .)
