Where a virgin is after a lion? (6)
I believe the answer is:
zodiac
'where a virgin is after a lion?' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
This is the entire clue.
(Other definitions for zodiac that I've seen before include "Houses seen on a cycle" , "17 Across is a sign of the ......." , "Heavenly belt of star-signs" , "nd of sky divided into twelve parts" , "Celestial region" .)
