Put excessive detail in sketch; it creates negative balance (8)
I believe the answer is:
overdraw
'negative balance' is the definition.
The answer and definition can be both to do with ownership as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'put excessive detail in sketch it' is the wordplay.
I cannot quite see how this works, but
'excessive' could be 'over' (over can mean in excess or excessively) and 'over' is found in the answer.
'sketch' could be 'draw' (I've seen this in other clues) and 'draw' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'creates' acts as a link.
Can you help me to learn more?
(Other definitions for overdraw that I've seen before include "Get into the red" , "Go into the red" , "incur debt" , "Use more money than you have in the bank" , "Exaggerate" .)
