Sign of spring in Cambridge minister (6)
I believe the answer is:
gemini
'sign' is the definition.
(Gemini is an example)
'of spring in cambridge minister' is the wordplay.
'of' indicates the answer is hidden within the clue.
'GEMINI' can be found hidden inside 'spring cambridge minister'.
(Other definitions for gemini that I've seen before include "Sign of the Twins ( 6)" , "May person" , "Third sign of the Zodiac" , "Twins star-sign" , "set of twinklers" .)
