Beloved patriot, a Romanian, taking part in revolution (9)
I believe the answer is:
inamorato
'beloved' is the definition.
(thesaurus)
'patriot a romanian taking part in revolution' is the wordplay.
'taking part' says the answer is hidden in the clue.
'in revolution' shows that the letters should be reversed in order.
'otaromani' is hidden in the letters of 'patriot a romanian'.
'otaromani' backwards is 'INAMORATO'.
(Other definitions for inamorato that I've seen before include "I Love A Lassie" , "One who's fond of" , "Male lover" , "Man loved" , "Italian lover" .)
