English reader with a list primarily of voters (9)
I believe the answer is:
electoral
'of voters' is the definition.
(I've seen this before)
'english reader with a list primarily' is the wordplay.
'english' becomes 'e' (abbreviation).
'reader' becomes 'lector' ('lector' can be a synonym of 'reader'**).
'with' is a charade indicator (letters next to each other).
'primarily' suggests taking the first letters.
The initial letter of 'list' is 'l'.
'e'+'lector'+'a'+'l'='ELECTORAL'
(Other definitions for electoral that I've seen before include "made up of voters" , "kind of US college" , "Relating to polls" , "on the voting register" , "concerned with votes" .)
