Feud in TA after check involving death (8)
I believe the answer is:
vendetta
'feud' is the definition.
(I know that feud can be written as vendetta)
'in ta after check involving death' is the wordplay.
'in' indicates putting letters inside.
'after' says to put letters next to each other.
'check' becomes 'vet' (to vet someone is to check their background).
'involving death' becomes 'end' (I can't justify this - if you can you should give a lot more credence to this answer).
'ta' after 'vet' is 'vetta'.
'vetta' enclosing 'end' is 'VENDETTA'.
Can you help me to learn more?
(Other definitions for vendetta that I've seen before include "Bitter feud between families" , "Long bitter row" , "A prolonged feud of Sicilian origin" , "Prolonged bitter quarrel" , "Violent feud" .)
