One of two Tudor kings (5)
I believe the answer is:
henry
'one of two tudor kings' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for henry that I've seen before include "CARRY ON FILM" , "Author of The Turn of the Screw" , "Best Actor Oscar winner 1981, for 'On Golden Pond'" , "O. -; US writer" , "Unit of inductance; man's name" .)
