Rents from the original landlord and relaxes (6)
I believe the answer is:
leases
'rents' is the definition.
(I've seen this in another clue)
'original landlord and relaxes' is the wordplay.
'original' suggests taking the first letters.
'and' is a charade indicator (letters next to each other).
'relaxes' becomes 'eases' (ease can mean to relax or reduce).
The initial letter of 'landlord' is 'l'.
'l'+'eases'='LEASES'
'from the' is the link.
(Other definitions for leases that I've seen before include "Enters into contract to use, say, land" , "Rents out" .)
