Tsarina cultivated a craftswoman (7)
I believe the answer is:
artisan
'a craftswoman' is the definition.
(I've seen this in another clue)
'tsarina cultivated' is the wordplay.
'cultivated' is an anagram indicator.
'tsarina' is an anagram of 'ARTISAN'.
(Other definitions for artisan that I've seen before include "man with skill" , "Skilled worker at craft or trade" , "crafty person?" , "Mechanic" , "Skilled worker or craftsman" .)
