Hood in America's gamble banking on Nitti, initially (6)
I believe the answer is:
bonnet
'hood in america's' is the definition.
'bonnet' can be an answer for 'hood' (synonyms). I'm not sure about the 'in america's' bit.
'gamble banking on nitti initially' is the wordplay.
'gamble' becomes 'bet' (bet is a kind of gamble).
'banking' is an insertion indicator.
'initially' says to take the initial letters.
The first letter of 'nitti' is 'n'.
'on'+'n'='onn'
'bet' placed around 'onn' is 'BONNET'.
Can you help me to learn more?
(Other definitions for bonnet that I've seen before include "Cover for head or engine" , "Over; mentioned earlier" , "Lady's old-fashioned hat" , "Headdress (for Easter?)" , "Old female headgear, once popular at Easter" .)
