The same turning, indicate left (9)
I believe the answer is:
identical
'the same' is the definition.
(I've seen this before)
'turning indicate left' is the wordplay.
'turning' indicates anagramming the letters.
'left' becomes 'l' (common abbreviation).
'indicate' with letters rearranged gives 'identica'.
'identica'+'l'='IDENTICAL'
(Other definitions for identical that I've seen before include "Equal" , "showing no change" , "Duplicate" , "Exactly alike, the same in every detail" , "not distinguished" .)
