Avoid result of decapitation (4,3)
I believe the answer is:
head off
'avoid' is the definition.
(I know that avoid can be written as head off)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for head off that I've seen before include "Block" , "Deflect (decapitated?)" , "Avoid" , "like Robespierre?" , "Intercept - at the pass?" .)
