Crooked dealing made straight (7)
I believe the answer is:
aligned
'straight' is the definition.
(similar in meaning)
'crooked dealing' is the wordplay.
'crooked' is an anagram indicator (a crooked or disrupted version of the letters).
'dealing' is an anagram of 'ALIGNED'.
'made' is the link.
(Other definitions for aligned that I've seen before include "made to toe the line" , "Linearly positioned" , "joined forces" , "Dealing (anag) - straight?" , "in a row" .)
