Some Spanish ruggedly showing sign of indifference (5)
I believe the answer is:
shrug
'sign of indifference' is the definition.
(I've seen this before)
'some spanish ruggedly showing' is the wordplay.
'showing' says the answer is hidden in the clue.
'SHRUG' can be found hidden inside 'some spanish ruggedly'.
(Other definitions for shrug that I've seen before include "Expressive shoulder movement" , "Gesture expressing unconcern" , "Expressive movement of shoulders" , "Sign of indifference" , "Gesture of uncertainty or not knowing" .)
