Actively pursued question about commercial featuring foxes for instance (10)
I believe the answer is:
quadrupeds
'commercial featuring foxes for instance' is the definition.
I can't judge whether this definition defines the answer.
'actively pursued question about' is the wordplay.
I cannot quite see how this works, but
'question' could be 'qu' and 'qu' is located in the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' 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?
(Another definition for quadrupeds that I've seen is " perhaps horses wanted".)
