Redistributing made sense, American having left more than one estate (8)
I believe the answer is:
demesnes
'more than one estate' is the definition.
('demesne' can be a synonym of 'estate')
'redistributing made sense american having left' is the wordplay.
'redistributing' is an anagram indicator (I've seen this in other clues).
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'having left' indicates named letters should be taken away.
'made'+'sense'='madesense'
'madesense' with 'a' removed is 'mdesense'.
'mdesense' with letters rearranged gives 'DEMESNES'.
(Other definitions for demesnes that I've seen before include "Lands attached to manors" , "landed properties" , "private lands" .)
