Arguments about Arab customs (7)
I believe the answer is:
tariffs
'customs' is the definition.
The definition and answer can be both related to property as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'arguments about arab' is the wordplay.
'arguments' becomes 'tiffs' (I've seen this before).
'about' indicates putting letters inside.
'arab' becomes 'Ar.' (abbreviation in reference works).
'tiffs' placed around 'ar' is 'TARIFFS'.
Can you help me to learn more?
(Other definitions for tariffs that I've seen before include "Lists of charges" , "List of customs duties or charges" , "taxes" .)
