Wish you had all that money back? Talk about bad luck! (10)
I believe the answer is:
misfortune
This could be a double definition.
'wish you had all that money back? talk' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'bad luck' is the second definition.
(synonyms)
'about' acts as a link.
Can you help me to learn more?
(Other definitions for misfortune that I've seen before include "DISASTER]" , "Adversity - bad luck" .)
