Flip a little battery out of the radio (10)
I believe the answer is:
somersault
'flip' is the definition.
(I know that flip can be written as somersault)
'a little battery out of the radio' is the wordplay.
I cannot quite understand how this works, but
'a' is within the answer.
'little' could be 'some' (similar in meaning) and 'some' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for somersault that I've seen before include "Move acrobatically" , "Acrobatic movement" , "Perform acrobatic feat" , "policy switch" , "Turn head over heels" .)
