Not just power tool user? (8)
I believe the answer is:
partisan
'tool user?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'not just power' is the wordplay.
I cannot quite see how this works, but
'power' could be 'art' (art is a kind of power) and 'art' is found within the answer.
The remaining letters 'pisan' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for partisan that I've seen before include "One-sided" , "Aspirant to be a guerilla" , "Enthusiastic supporter" , "Resistance fighter" , "Prejudiced towards one side" .)
