Painter enthralling residents to some extent (6)
I believe the answer is:
ingres
'painter' is the definition.
(thesaurus)
'enthralling residents to some extent' is the wordplay.
'to some extent' indicates the answer is hidden within the clue.
'INGRES' is hidden in the letters of 'enthralling residents'.
(Other definitions for ingres that I've seen before include "French painter of elegant portraits" , "Producer of old pictures" , "Jean -; Fr. artist; singer (anag.)" , "French classical painter" , "French painter; singer (anag)" .)
