It's odd about the taxes (6)
I believe the answer is:
tithes
'taxes' is the definition.
The definition and answer can be both related to property as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'it's odd about the' is the wordplay.
'odd' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'its' anagrammed gives 'tis'.
'tis' enclosing 'the' is 'TITHES'.
Can you help me to learn more?
(Other definitions for tithes that I've seen before include "Tenth parts, levied by some churches" , "Tenths of income once paid to church" , "Tenths of income given to church" , "Church taxes" , "Tenth parts, levied by a church perhaps" .)
