Came back with plans we redrafted somewhat (8)
I believe the answer is:
answered
'came back' is the definition.
(I've seen this in another clue)
'plans we redrafted somewhat' is the wordplay.
'somewhat' indicates a hidden word.
'ANSWERED' is hidden in the letters of 'plans we redrafted'.
'with' acts as a link.
(Other definitions for answered that I've seen before include "Fulfilled" , "Returned" , "Replied or responded" , "Rejoined" , "succeeded" .)
