American style bonnet (4)
I believe the answer is:
hood
This could be a double definition.
'american style' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'bonnet' is the second definition.

Can you help me to learn more?
