abstract

I'm a little stuck... Click here to teach me more about this clue!

'remove' is the definition.
(thesaurus)

'pollock work for one' is the wordplay.
I cannot really understand how this works, but
'work' could be 'act' ('act' can be a synonym of 'work') and 'act' is found in the answer.
'one' could be 'a' and 'a' is found in the answer.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for abstract that I've seen before include "Appropriate - theoretical - summary" , "Take away - theoretical" , "Nick" , "Extract; summary" , "Rothko work?" .)
