Generous provision for Braille (7)

I believe the answer is:

liberal

I'm a little stuck... Click here to teach me more about this clue!

'generous' is the definition.
(similar in meaning)

'provision for braille' is the wordplay.
'braille' can be anagrammed to 'LIBERAL'.
Though, I am unsure how this is indicated.

Can you help me to learn more?

(Other definitions for liberal that I've seen before include "Lavish" , "Politically progressive" , "Generous; broad-minded" , "Large-minded" , "Bountiful" .)

I've seen this clue in The Irish Independent.
