Free to get another tenant (7)
I believe the answer is:
release
'free' is the definition.
(to release someone is to free them)
'get another tenant' is the wordplay.
I cannot really understand how this works, but
'get' could be 'lease' (leasing is a kind of getting) and 'lease' is found in the answer.
'another' could be 're' (I've seen this in other clues) and 're' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for release that I've seen before include "Possibly film" , "Authorise publication" , "Let go" , "Issue" , "put out" .)
