Deliver large skewers for butcher (4)
I believe the answer is:
slay
'butcher' is the definition.
(both can mean to murder)
'deliver large skewers' is the wordplay.
'deliver' becomes 'say' (deliver can mean to say out loud).
'large' becomes 'L' (eg in clothes sizes).
'skewers' is an insertion indicator (inserted letters skewer into others).
'say' placed around 'l' is 'SLAY'.
'for' acts as a link.
(Other definitions for slay that I've seen before include "Butcher" , "Kill, murder" , "Fatally hit" , "Kill (literary)" , "Kill intentionally" .)
