Special edition's text, rather reduced (5)
I believe the answer is:
extra
'special edition's' is the definition.
(I've seen this in another clue)
'text rather reduced' is the wordplay.
'reduced' indicates a hidden word (reducing the letters in the clue shows the answer).
'EXTRA' is hidden in the letters of 'text rather'.
(Other definitions for extra that I've seen before include "comes to 16 [TEST MATCH]" , "Additional or supplementary" , "like one of the crowd" , "Crowd-scene actor" , "one added to the score" .)
