It's curtains for the Yanks! (6)
I believe the answer is:
drapes
'it's curtains for the yanks' is the definition.
(US term for curtains)
'it's' is the wordplay.
I cannot really understand how this works, but
'it's' could be 'es' ('e' can mean 'electronic' which is similar to 'IT') and 'es' is located in the answer.
The remaining letters 'drap' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for drapes that I've seen before include "screens in Windows" , "Hangs (cloth) loosely" , "Long curtains" , "Curtains for padres" , "Spread like curtains" .)
