Person in temporary accommodation is more obviously affected (6)
I believe the answer is:
camper
'person' is the definition.
(camper is a kind of person)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for camper that I've seen before include "One with temporary home" , "Person under canvas" , "One using tent" , "Large motor vehicle with beds, cooker etc" , "more affected?" .)
