Generous representation of Braille (7)
I believe the answer is:
liberal
'generous' is the definition.
('liberal' can be similar in meaning to 'generous')
'representation of braille' is the wordplay.
'representation of' indicates anagramming the letters (I've seen this in other clues).
'braille' with letters rearranged gives 'LIBERAL'.
(Other definitions for liberal that I've seen before include "Favouring a political philosophy of progress and reform" , "Permissive about Braille" , "Braille (anag.)" , "Generous; broad-minded" , "open to new ideas" .)
