Feint bringing endless disgrace (4)
I believe the answer is:
sham
'feint' is the definition.
(I know that feint is a more specific form of sham)
'endless disgrace' is the wordplay.
'endless' means to remove the last letter.
'disgrace' becomes 'shame' (synonyms).
'shame' with its final letter taken off is 'SHAM'.
'bringing' acts as a link.
(Other definitions for sham that I've seen before include "Cheap falseness" , "Pretence, hoax" , "'Fake, pseudo (4)'" , "Phoney kind of hams" , "Unreal" .)
