Turkish leader is a little extravagant (3)
I believe the answer is:
aga
'turkish leader' is the definition.
(I've seen this in another clue)
'a little extravagant' is the wordplay.
'a little' indicates a hidden word (a little bit of the clue).
'AGA' can be found hidden inside 'extravagant'.
'is' acts as a link.
(Other definitions for aga that I've seen before include "In Turkey, an official" , "Proprietary name for a domestic stove" , "Cook's equipment" , "Swedish stove" , "military leader" .)
