dweller (8)
I believe the answer is:
resident
'dweller' is the definition.
(I know that dweller can be written as resident)
This is the entire clue.
(Other definitions for resident that I've seen before include "Inserted by permanent inhabitant" , "one in the house?" , "Inhabitant, occupant" , "Hotel guest staying for a prolonged period" , "One living in the place referred to" .)
