Naughty dog, say, turned on kids’ programme (4,5)
I believe the answer is:
blue peter
'kids' programme' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'naughty dog say turned on' is the wordplay.
'naughty' becomes 'blue' (synonyms).
'dog say' becomes 'pet' (dog is an example).
'turned' says the letters should be written in reverse.
'on' becomes 're' (regarding).
're' back-to-front is 'er'.
'blue'+'pet'+'er'='BLUE PETER'
Can you help me to learn more?
(Other definitions for blue peter that I've seen before include "BBC children's programme" , "Signal flag - children's TV programme" , "Flag to show a vessel is ready to sail" , "Flag flown to warn of a ship's departure" , "Flag showing ship is about to leave" .)
