Painter decorating residences in the centre (6)
I believe the answer is:
ingres
'painter' is the definition.
(thesaurus)
'decorating residences in the centre' is the wordplay.
'in the centre' indicates a hidden word.
'INGRES' is hidden in the letters of 'decorating residences'.
(Other definitions for ingres that I've seen before include "French artist" , "Jean -; Fr. artist; singer (anag.)" , "French painter of elegant portraits" , "French painter; singer (anag)" , "Odalisque painter" .)
