Criticise old master stealing artist's landscape? (8)
I believe the answer is:
panorama
'landscape?' is the definition.
(thesaurus)
'criticise old master stealing artist's' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'master' becomes 'ma'.
'stealing' is an insertion indicator.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'o'+'ma'='oma'
'oma' placed around 'ra' is 'orama'.
'pan'+'orama'='PANORAMA'
(Other definitions for panorama that I've seen before include "Picture" , "Wide view of region" , "Wide unbroken view" , "Unbroken view of surrounding area" , "Wide-angle shot" .)
