Bloody extraordinary! (4)
I believe the answer is:
rare
I believe this is a double definition.
'bloody' is the first definition.
(I've seen this before)
'extraordinary' is the second definition.
(I've seen this in another clue)
(Other definitions for rare that I've seen before include "Very scarce, like undercooked steak" , "Infrequent like underdone meat" , "not often spotted" , "Seldom seen or met" , "Exceptionable" .)
