Poets I'd incorrectly set down (7)
I believe the answer is:
deposit
'set down' is the definition.
(I've seen this before)
'poets i'd incorrectly' is the wordplay.
'incorrectly' indicates an anagram (I've seen this in other clues).
'poets'+'id'='poetsid'
'poetsid' is an anagram of 'DEPOSIT'.
(Other definitions for deposit that I've seen before include "Layer laid down" , "Money given as security" , "part-payment" , "is one back on the bottle?" , "Plant" .)
