Theoretical art from Pollock? (8)
I believe the answer is:
abstract
'theoretical' is the definition.
(synonyms)
'art from pollock?' is the wordplay.
I cannot really see how this works, but
an anagram of 'art' is 'tra' which is within 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 abstract that I've seen before include "Nick" , "Sketchy summary of the main points" , "Theoretical, not physical" , "Academic" , "Brats act in non-concrete way" .)
