She's brazen but possibly shy about the Americans (5)

I believe the answer is:
hussy
'she's brazen' is the definition.
I can't tell whether this definition defines the answer.
'possibly shy about the americans' is the wordplay.
'possibly' indicates an anagram.
'about' indicates putting letters inside.
'the americans' becomes 'US' (United States).
'shy' anagrammed gives 'hsy'.
'hsy' placed around 'us' is 'HUSSY'.
'but' is the link.
Can you help me to learn more?
(Other definitions for hussy that I've seen before include "Shameless woman" , "Immoral woman" , "Trollop" , "tart" , "An impudent or brazen girl" .)
