Sign of partial forgiveness, possibly? (5)

I believe the answer is:

virgo

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

'sign' is the definition.
(I know this)

I can't explain the rest of the clue.

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

I've seen this clue in the Evening Standard.
