Old-time artist gives more (5)
I believe the answer is:
extra
'more' is the definition.
(I've seen this in other clues)
'old-time artist' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'time' becomes 't' (abbreviation).
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'ex'+'t'+'ra'='EXTRA'
'gives' is the link.
(Other definitions for extra that I've seen before include "Accessory" , "No great contribution to film" , "Ancillary" , "fortuitous run" , "not included" .)
