Turn over again (6)
I believe the answer is:
encore
This clue might be a double definition.
'turn over' is the first definition.
'encore' can be an answer for 'over' (thesaurus). I'm not sure about the 'turn' bit.
'again' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for encore that I've seen before include "Bis!" , "Sing it again, please" , "Play or sing it again" , "(Call for) repeat performance" , "Cry from the audience for more" .)
