Bad-tempered woman ignoring a sign (5)
I believe the answer is:
virgo
'sign' is the definition.
(Virgo is an example)
'bad-tempered woman ignoring a' is the wordplay.
'bad-tempered woman' becomes 'virago' (I've seen this before).
'ignoring' indicates named letters should be taken away.
'virago' with 'a' taken out is 'VIRGO'.
(Other definitions for virgo that I've seen before include "Zodiacal sign" , "Large constellation between Leo and Libra" , "A constellation, a cluster" , "Sixth sign of zodiac" , "Large constellation -- sign of the zodiac" .)
