Bloody tragic king’s watery-eyed (5)
I believe the answer is:
blear
'watery-eyed' is the definition.
'bloody tragic king's' is the wordplay.
'bloody' becomes 'b' (as a swear word it might be censored as 'b-----').
'tragic king' becomes 'lear' (I've seen this before).
'b'+'lear'='BLEAR'
(Other definitions for blear that I've seen before include "Watery, blurred" , "Make (the eyes) dim" , "Blur" , "Indistinct" , "Baler (anag.)" .)
