Created a stir when curbing deafening customs (7)
I believe the answer is:
tariffs
'deafening customs' is the definition.
The answer and definition can be both related to property as well as being plural nouns.
Perhaps you can see a link between them that I don't see?
'created a stir when curbing' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'when' could be 'if' and 'if' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tariffs that I've seen before include "List of customs duties or charges" , "taxes" , "Lists of charges" .)
