English artist shows age (3)
I believe the answer is:
era
'age' is the definition.
(thesaurus)
'english artist' is the wordplay.
'english' becomes 'e' (abbreviation).
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'e'+'ra'='ERA'
'shows' is the link.
(Other definitions for era that I've seen before include "Series of years" , "Memorable period" , "Stage" , "Characteristic period" , "Aeon" .)
