Girl presenting French art to the King (6)
I believe the answer is:
esther
'girl' is the definition.
'french art to the king' is the wordplay.
'french art' becomes 'es' ('is' in French - 'art' can mean 'is' eg 'thou art').
'king' becomes 'R' (abbreviation of Latin rex).
'es'+'the'+'r'='ESTHER'
'presenting' is the link.
(Other definitions for esther that I've seen before include "Old Testament book that tells of a beautiful Jewess" , "Fem. name, threes (anag.)" , "__ Rantzen, TV presenter, b. 1940" , "OT Queen of Persia" , "Oratorio by Handel; girl's name" .)
