Substitute some workers at zoo (6)

Ross

I believe the answer is:

ersatz

'substitute' is the definition.
(I know that ersatz is a type of substitute)

'some workers at zoo' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ERSATZ' is hidden in the letters of 'workers at zoo'.

(Other definitions for ersatz that I've seen before include "Spurious" , "Substitute - fake" , "Imitation, not the real thing" , "Imitation or substitute, from German" , "unnatural" .)

I've seen this clue in The Times.
