Temporary shelter accommodating a new resident (6)
I believe the answer is:
tenant
'resident' is the definition.
(tenant is a kind of resident)
'temporary shelter accommodating a new' is the wordplay.
'temporary shelter' becomes 'tent' (I've seen this before).
'accommodating' means one lot of letters goes inside another.
'a new' becomes 'an' (I've seen this in other clues).
'tent' going around 'an' is 'TENANT'.
(Other definitions for tenant that I've seen before include "Someone who pays rent" , "Occupier of rented property" , "Occupier but not owner" , "Property renter" , "One renting property" .)
