New acts due to support English schools (8)
I believe the answer is:
educates
'schools' is the definition.
('educate' can be a synonym of 'school')
'new acts due to support english' is the wordplay.
'new' indicates an anagram.
'to support' means one lot of letters go next to another (in a down clue, some letters hold others up).
'english' becomes 'e' (abbreviation).
'acts'+'due'='actsdue'
'actsdue' is an anagram of 'ducates'.
'ducates' put after 'e' is 'EDUCATES'.
(Other definitions for educates that I've seen before include "Trains, teaches" , "Instructs, teaches" , "Trains the mind and abilities" .)
