Some real gold star (5)
I believe the answer is:
algol
'star' is the definition.
(Algol is an example)
'some real gold' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'ALGOL' is hidden in the letters of 'real gold'.
(Other definitions for algol that I've seen before include "language (but not used in speech)" , "Star" , "Computer language" .)
