Piece of old film on medical procedure put back in (2-5)
I believe the answer is:
re-elect
'medical procedure put back in' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'piece of old film on' is the wordplay.
'piece of old' becomes 'ect' (I can't explain this - if you can you should give a lot more credence to this answer).
'film' becomes 'reel' (reel is a kind of film).
'on' is a charade indicator (letters next to each other).
'ect' after 'reel' is 'RE-ELECT'.
Can you help me to learn more?
(Other definitions for re-elect that I've seen before include "Bring to power again" , "Put into power again" , "Vote in again" .)
