I believe the answer is:

virgo

I'm a little stuck... Click here to teach me more about this clue!

'zodiacal sign' is the definition.
(I've seen this in another clue)

I can't explain the rest of the clue.

(Other definitions for virgo that I've seen before include "number of stars" , "Zodiacal sign" , "A constellation, a cluster" , "Large constellation between Leo and Libra" , "Sixth sign of zodiac" .)

I've seen this clue in the Evening Standard.
