English artist showing 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'
'showing' is the link.
(Other definitions for era that I've seen before include "Age of importance" , "Long stretch" , "Epoch, period" , "generation, maybe" , "Characteristic period" .)
