Greatest artist has a beginning (5)

I believe the answer is:

start

'a beginning' is the definition.
(start is a kind of beginning)

'greatest artist has' is the wordplay.
'has' indicates a hidden word.
'START' is hidden in the letters of 'greatest artist'.

(Other definitions for start that I've seen before include "begin an argument?" , "Set in motion" , "open" , "Begin with sudden movement of surprise" , "Begin - opening move" .)

I've seen this clue in The Daily Express.
