Guardian Prize

Puzzle, I think, solved - but can anyone help with parsing 3 solutions:
8d Audibly don't eat in Yorkshire? Don't listen. T_N_ O_T. Presumably TUNE OUT - but why, apart from fitting definition?
22d Among maestri, one raised towards the heavens as an artist. _E_O_R. Presumably RENOIR and I get the reversed 'one', but how does the rest of it work?
25d Easy crossword solution (5) L_G_T. Presumably light and near synonym of 'easy', but don't see the rest of its. Thanks in anticipation.

22d RENOIR - backwards in clue

[Captain2]

maestRI ONE Raised

[Captain2]

8d Don't eat in Yorkshire would be 'Chew Nowt' sounds like Tuned Out

[Captain2]

25 A square in a crossword is called a 'light'?

[Cryptomaniac]

Thanks Captain! Am kicking myself for not seeing/hearing the 'chew nowt'. But is it the crossword clue - rather than a square - which is the 'light', i.e. the clue casts light on the solution?

Light

BRITISH
(in a crossword puzzle) a blank space to be filled by a letter.

Not quite - a light is a SERIES OF CELLS in a crossword grid, where your entry goes. A lot of dictionaries get this wrong.
