Country artist cracks one question (4)
I believe the answer is:
iraq
'country' is the definition.
(Iraq is an example)
'artist cracks one question' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'cracks' indicates putting letters inside (some letters create an opening in the word).
'one' becomes 'I' (Roman numeral).
'question' becomes 'q'.
'i'+'q'='iq'
'ra' inserted within 'iq' is 'IRAQ'.
(Other definitions for iraq that I've seen before include "Middle East republic, capital Baghdad" , "Present-day site of Mesopotamia" , "Middle East country" , "Basra's country" , "Country of Baghdad and Basra" .)
