Artisan working for Russian empress (7)
I believe the answer is:
tsarina
'russian empress' is the definition.
(I've seen this before)
'artisan working' is the wordplay.
'working' indicates an anagram.
'artisan' is an anagram of 'TSARINA'.
'for' acts as a link.
(Other definitions for tsarina that I've seen before include "Foreign ruler" , "aristocratic woman" , "Wife of a tsar" , "Wife of former Russian ruler" , "Consort" .)
