Artist has a turn to speak on Scottish isle (6)

'scottish isle' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'artist has a turn to speak' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'has' is a charade indicator (letters next to each other).
'turn to speak' becomes 'say'' (I've seen this in another clue).
'ra'+'a'+'say'='RAASAY'

'on' acts as a link.

Can you help me to learn more?
