Petrarch's beloved (5)
I believe the answer is:
laura
'petrarch's beloved' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for laura that I've seen before include "Girl's name" , "1944 American film noir directed by Otto Preminger" , "__ Ashley, Welsh fashion and textile designer, d. 1985" , "- Ashley, Welsh clothes, furnishings designer" , "Petrarch loved her" .)
