Pulled too much into the red (9)
I believe the answer is:
overdrawn
'red' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives sometimes define each other.
'pulled too much into the' is the wordplay.
I cannot really see how this works, but
'pulled' could be 'drawn' ('draw' can be a synonym of 'pull') and 'drawn' is found within the answer.
'too much' could be 'over' (I've seen this in other clues) and 'over' is found in the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for overdrawn that I've seen before include "In the red at the bank" , "Cartoonishly exaggerated" , "account discredited" , "got into debt" , "having incurred obligations" .)
