Bold Aussie currency, ciao povera America! (9)
I believe the answer is:
audacious
'bold' is the definition.
(similar in meaning)
'aussie currency ciao povera america' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'ciao' is 'acio' which is located in the answer.
'america' could be 'us' (United States) and 'us' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for audacious that I've seen before include "Risky" , "Bold - impertinent" , "Recklessly daring" , "Dare-devil" , "Recklessly bold" .)
