Renter leaving article in temporary accommodation (6)
I believe the answer is:
tenant
'renter' is the definition.
('tenant' can be a synonym of 'renter')
'article in temporary accommodation' is the wordplay.
'article' becomes 'an' (indefinite article).
'in' is an insertion indicator.
'temporary accommodation' becomes 'tent' (I've seen this before).
'an' going within 'tent' is 'TENANT'.
'leaving' is the link.
(Other definitions for tenant that I've seen before include "Person renting property" , "Occupier of rented property" , "one paying rent" , "One who pays rent" , "individual bound by lease" .)
