Sign of equilibrium? (5)
I believe the answer is:
libra
This could be a double definition.
'sign' is the first definition.
(sign of the zodiac)
'equilibrium?' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'of' is the link.
Can you help me to learn more?
(Other definitions for libra that I've seen before include "Scales constellation" , "Scales star sign" , "Zodiac sign of the scales" , "stars" , "Someone born between September 23 and October 22" .)
