Confused theologian caught in crooked deal (6)
I believe the answer is:
addled
'confused' is the definition.
(addling is a kind of confusing)
'theologian caught in crooked deal' is the wordplay.
'theologian' becomes 'DD' (Doctor of Divinity degree).
'caught in' indicates putting letters inside.
'crooked' is an anagram indicator.
'deal' is an anagram of 'aled'.
'dd' placed within 'aled' is 'ADDLED'.
(Other definitions for addled that I've seen before include "spoiled" , "Befuddled" , "Foolish or confused like bad egg" , "Scatterbrained like bad egg" , "Confused, mixed up like bad egg" .)
