Differences of opinion about gas rates (7)
I believe the answer is:
tariffs
'rates' 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 can't see?
'differences of opinion about gas' is the wordplay.
'differences of opinion' becomes 'tiffs' (I can't explain this - if you can you should give a lot more credence to this answer).
'about' means one lot of letters goes inside another.
'gas' becomes 'ar' (I've seen this in other clues).
'tiffs' placed around 'ar' is 'TARIFFS'.
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" .)
