Covered passage having a twisted cedar (6)
I believe the answer is:
arcade
'covered passage' is the definition.
(I've seen this before)
'a twisted cedar' is the wordplay.
'twisted' indicates anagramming the letters.
'cedar' anagrammed gives 'rcade'.
'a'+'rcade'='ARCADE'
'having' acts as a link.
(Other definitions for arcade that I've seen before include "covered avenue of shops" , "Covered passage containing shops" , "Covered walkway with shops" , "Arched passageway between shops" , "Covered way with shops on either side" .)
