Processed docket, only deducting $1000 on first leaf? (9)
I believe the answer is:
cotyledon
'leaf?' is the definition.
(I know that cotyledon is a type of cataphyll)
'processed docket only deducting $1000 on first' is the wordplay.
I cannot really understand how this works, but
'on' is found in 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 cotyledon that I've seen before include "First green shoot" , "New growth" , "leafing through this?" .)
