Free rent again? (7)
I believe the answer is:
release
'free' is the definition.
(to release someone is to free them)
'rent again?' is the wordplay.
I cannot quite understand how this works, but
'rent' could be 'lease' (I've seen this in another clue) and 'lease' is found within the answer.
'again?' could be 're' (prefix meaning 'again') and 're' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for release that I've seen before include "Possibly film" , "Free - delivery" , "press announcement" , "Authorise publication" , "Free from confinement" .)
