Cover of Kids on the radio (5)
I believe the answer is:
guise
'cover of kids on the radio' is the definition.
'guise' can be an answer for 'cover' (thesaurus). I am unsure of the 'of kids on the radio' bit.
'cover of kids on the radio' is the wordplay.
'cover of' suggests removing the centre (only the letters which cover the word).
'kids' becomes 'imps' (imp is a kind of kid).
'on' means one lot of letters goes inside another.
'the radio' becomes 'gue' (I am not sure about this - if you are sure you should believe this answer much more).
'imps' with its centre taken out is 'is'.
'is' going within 'gue' is 'GUISE'.
Can you help me to learn more?
(Other definitions for guise that I've seen before include "General appearance" , "Show" , "Demeanour" , "Shape; pretence" , "Mask" .)
