In the middle of parade, ladies bop when it's played (5)
I believe the answer is:
radio
'it's played' is the definition.
I can't tell whether this definition defines the answer.
'in the middle of parade ladies bop' is the wordplay.
'in the middle of' means to look at the middle letters (I've seen 'in the middle' mean this).
'ladies bop' becomes 'dio' (I am not sure about this - if you are sure you should believe this answer much more).
The middle letters of 'parade' are 'ra'.
'ra'+'dio'='RADIO'
'when' is the link.
Can you help me to learn more?
(Other definitions for radio that I've seen before include "Broadcast medium" , "Communications receiver" , "Speech receiver" , "MW, LW or FM sound source" , "Communicate with" .)
