restart

'is a new beginning' is the definition.
I can't judge whether this definition defines the answer.

'relax painting' is the wordplay.
'relax' becomes 'rest' (to relax is to have a rest).
'painting' becomes 'art' (painting is an art).
'rest'+'art'='RESTART'

Can you help me to learn more?

(Other definitions for restart that I've seen before include "Commence again" , "Jumping the gun will mean" , "Begin anew" , "Resume" , "launch again" .)

I've seen this clue in The Daily Express.
